Major Manufacturing's HIT-66 System

Introduction

Major Manufacturing’s HIT-66 System is one of the most ubiquitous installation tools in the locksmith industry. It allows locksmiths to perform professional installations of the most popular cylindrical and mortise locks with amazing efficiency.

HIT-66 Clamp System

HIT-66 Clamp System


The basis of the HIT-66 is it’s clamp system. All other tools in the HIT-66 family attach to these rubber-lined clamps. The clamps fit doors ranging from 1-1/4” to 2-7/8” and are machined from aluminum.

The HIT-66-100 is, for all intents and purposes, an installation template for any lock requiring a 160 or 161 prep. It can perform fresh installations or enlarge existing crossbores. It works on wood and steel doors and can accommodate 2-3/8″ and 2-3/4″ backsets. It features 5/16″ holes for through-bolts at the 6 and 12 o’clock positions. The latchbore can be drilled with either an auger, brad-point, multi-point, or hole saws with the supplied adapters.

The HIT-66-200 is an attachment that mortises pockets for mortise locks. It directly attaches to the HIT-66 clamp system and can be used in conjunction with nearly all other HIT-66 templates at the same time. This allows you to perform a fresh installation of almost all popular mortise locks currently on the market. It comes with a 1″ carbide-tip mortising bit along with stop collars.

HIT-66 Templates

Mortise lock templates are the shining stars of the HIT-66 system. These templates allow you to accurately and quickly drill cylinder, thumbturn, trim, and all other auxiliary holes for the most popular mortise locks. The following templates are available from Major to work with the HIT-66:

  • HIT-66-210 (Alarm Lock DL3500)
  • HIT-66-230 (Best 34H/37H/45H/47H)
  • HIT-66-235 (Corbin Russwin ML2000/ML2200)
  • HIT-66-240 (Falcon MA)
  • HIT-66-248 (Hager 3800)
  • HIT-66-250 (Kaba E-Plex/5000)
  • HIT-66-251 (Kaba 660/760/770/790)
  • HIT-66-255 (Marks 5/DORMA M9000)
  • HIT-66-263 (Onity CT)
  • HIT-66-264 (Onity HT)
  • HIT-66-266 (Saflok MT)
  • HIT-66-268 (Salto XS-4)
  • HIT-66-272 (Sargent 7800/7900/8200/9200)
  • HIT-66-280 (Schlage AD)
  • HIT-66-281 (Schlage CO)
  • HIT-66-282 (Schlage L)

Using the HIT-66

The HIT-66 is one of the easiest installation tools to use. In this example, I’m going to show you how it works by using the HIT-66-282 template for Schlage L Series mortise locks.
This door has a Schlage L9070 (Classroom function) mortise lock. It needs to be converted to a L9050 (Office/Inner Entry function). This means that the hole for the thumbturn hole needs to be drilled.

To start, the existing lock must be removed.

Once the lock is removed, we can begin attaching the HIT-66 and template. We start first by attaching the positioning plate. This helps orient the rest of the HIT-66 tool.

With the positioning plate install, we can now mount the rest of the HIT-66. The HIT-66 slides over the post of the positioning tool and is then pressed against the edge of the door. The clamps can then be tightened.

With the HIT-66 mounted, we can now drill. Since we only have to drill for the thumbturn, we identify that hole and drill.

Introductory Locksmithing: Lock Functions

Introduction

Locks come in a variety of shapes, sizes, finishes, backsets, etc. These features were implemented to fill needs. Lock functions too were designed to fill needs. Situations exist where a door should always be locked, when it should never be locked, or when it should do X or Y. Locks with a variety of functions were and are therefore necessary to meet the needs of these situations. 

function n. a set of operating features for a particular type of lock or exit device which make it suitable for a specific application. The function is designated by a classification name or standards reference number. See ANSI or BHMA for a specific listing.

ANSI/BHMA’s Role

ANSI/BHMA standards both define and assign names and numbers (known primarily as function numbers but also as ANSI numbers or function codes) to functions. The use of function descriptions, names, and numbers is commonly associated with 2 lock types:  

  1. ANSI/BHMA A156.2 (Bored & Preassembled Locks and Latches) covers bored locks, such as cylindrical knobsets and leversets.  
  1. ANSI/BHMA A156.13 (Standard for Mortise Locks and Latches) covers mortise locks.  

While technically bored locks, interconnected locks and their functions are defined in their own standard, ANSI/BHMA A156.12 (Interconnected Locks & Latches); I will use the “cylindrical” nomenclature for the remainder of this article to avoid any confusion. 
Other lock types, such as deadbolts and even cylinders, have functions defined and assigned names and numbers by ANSI/BHMA standards. Mortise locks and cylindrical locksets will be the focus of this article since they carry many more functions than the aforementioned lock types. 

Standardization

Standardizing functions helps bring uniformity to our industry. All manufacturers include function names and numbers in their catalogs. If you were searching for a specific function across multiple product lines, seeing this function name and number would tell you how the lock operates regardless of the manufacturer or their product number. For example, a Schlage L9010 and a Sargent 8215 are passage function (F01) mortise locks. Here is a side by side comparison of their catalog entries, each with their function number listed: 

Sargent and Schlage F01 comparison.

Sargent and Schlage F01 comparison.

Unique Functions

There are multiple functions that manufacturers offer that ANSI/BHMA standards don’t define or quantify. This is especially true for mortise locks which can incorporate more features, such as a deadbolt, than cylindrical knob and leversets. For example, Schlage’s L Series mortise locks has 57 functions – less than half have a corresponding ANSI/BHMA function name or number. Fortunately, all manufacturers include drawings as well as thorough descriptions for functions that ANSI/BHMA standards don’t cover. This eliminates any guess work.  
A clear majority of the locks that we sell or service have a function name and number. With a bit of familiarity and practice, their identification will be as second nature as identifying a tool in your tool box. In this article, we’re going to discuss the most common functions, their features, and where they are generally found to help build this familiarity. I’ve included descriptions, names, and numbers from Schlage’s L (mortise) and ND (cylindrical) series locks to help illustrate each function discussed. 

Function Terminology

Before we do that, let’s take a moment to cover some terminology. When describing a lock, we need to differentiate between each side of the door. Avoid using terms like secured side. This causes confusion over interpretation. Use the terms “outside” and “inside” instead. Outside refers to the side of the door which houses the cylinder; manufacturers will sometime refer to this as the “cylinder side” of the door. Inside nearly always refers to the side of the door without a cylinder. There are functions with cylinders on both sides of the door but the manufacturer will adequately describe these functions. This is the terminology used by manufacturers and it would serve you well to not only understand it but also practice it.  

Popular Functions

Popular Schlage ND Series (Grade 1, Cylindrical Leverset) Functions

Passage (F01 for mortise, F75 for cylindrical) 

Schlage L Series (Mortise Lock) Passage Function (F01).

Schlage L Series (Mortise Lock) Passage Function (F01).


The good thing about functions is that their name gives us clues to their use or operation. Passage function locks are a good example of this. They allow passage no matter which side of the door you are on. No key is required and passage locks cannot be locked. 
Passage function locks are ideal where doors are either required, such as by code, or desired to latch but not lock. Examples of their usage include common areas and on stairwell doors. They are also commonly used in conjunction with deadbolts where allowed. 

Privacy (F02, F19, or F22 for mortise, F76 for cylindrical) 

Schlage L Series (Mortise Lock) Bath/Bedroom Privacy Function (F22).

Schlage L Series (Mortise Lock) Bath/Bedroom Privacy Function (F22).


Privacy function locks allow an occupant inside of a room to lock the door from the inside via a thumbturn or push button. Turning the inside trim retracts the latch and/or deadbolt. Furthermore, there is an emergency override on the outside that a user can operate with a coin, standard screwdriver, or similar object that allows them to open the door in the event of an emergency. For mortise locks, F22 utilizes a latchbolt, no deadbolt. F02 and F19 incorporate a deadbolt. On F19 function mortise locks, the latch cannot be retracted by the outside trim when the deadbolt is thrown, on F02 function mortise locks it can (the latch and deadbolt operate independently). Privacy function locks are common on restroom doors as well as interior residential doors.  

Office/Entrance (F04 for mortise, F82 for cylindrical) 

Schlage L Series (Mortise Lock) Office/Inner Entry Function (F04).

Schlage L Series (Mortise Lock) Office/Inner Entry Function (F04).


Office/Entrance function mortise locks allow the room’s occupant to lock a door by utilizing a key and either a thumbturn or a toggle switch. Some manufacturers offer both types. For locks utilizing a toggle switch,you can only lock the door using the toggle switch. The door remains locked when turning the inside trim and using a key only retracts the latch. The toggle switch must be returned to the unlocked position to unlock the outside trim. For locks utilizing a thumbturn, the door can be locked using a key or the thumbturn. The door remains locked when turning the inside trim. The door can be unlocked by the key or by returning the thumbturn to the unlocked position.   
For cylindrical locks, F109 (Entrance Function) is very similar to F82. In fact, most people refer to them both as entrance function locks. The difference is that F109 function cylindrical locks utilize a turn-and-push button on the inside. Pushing the button will lock the door until you turn the inside trim or use the outside key to unlock it. Pushing and turning the button will lock the door indefinitely; the button must be turned back to the “push” position for it to be unlocked the next time the inside trim is turned or the key is used. Office/Entrance function locks are very popular on residences and individual commercial offices and closets. 

Storeroom (F07 for mortise, F86 for cylindrical) 

Schlage L Series (Mortise Lock) Storeroom Function (F07).

Schlage L Series (Mortise Lock) Storeroom Function (F07).


Storeroom function locks always remained locked from the outside and unlocked from the inside. You can use a key to retract the latch but that will not unlock the lock. A storeroom function lock prevents someone from inadvertently leaving the door unlocked. Storeroom function locks are popular on rooms containing sensitive information, such as server rooms, or items, such as storage rooms. Storeroom function locks are also popular with doors utilizing electric strikes. This prevents someone from unlocking the lock, relying instead on the electric strike, while still allowing for a mechanical override if necessary. 
Most manufacturers now offer storeroom function cylindrical leversets with “clutched” levers. Standard storeroom function cylindrical leversets have rigid outside levers whereas clutched levers are not; they allow movement of the outside lever without retracting the latch. This protects against destructive entry attempts to open a cylindrical leverset by forcing the outside lever trim. 

Classroom (F05 for mortise, F84 for cylindrical)

Schlage L Series (Mortise Lock) Classroom Function (F05).

Schlage L Series (Mortise Lock) Classroom Function (F05).


Classroom locks are very popular on, you guessed it, classrooms. The function allows only key holders, such as teachers or other school staff, to lock and unlock the outside trim of the lock. You don’t want to give students or other individuals the ability to lock the teacher out, after all! 
It’s important to note that new hardware products and lock functions are being developed by manufacturers to help protect classrooms in the event of an active shooter or similar threat. Furthermore, life safety codes related to this specific situation are actively being debated, researched, and, in some cases, revised in response. The usage of the term “classroom” is highly popular with these new functions. I cannot stress how important it is to verify the function of these locks as well as their legality in your jurisdiction before choosing to service or install them.  

Other Functions 

Passage, privacy, storeroom, entrance, and classroom functions are by far the most popular and utilized lock functions currently. You can satisfy a large majority of customer’s requests with these functions alone. There are, however, dozens more functions available. It would serve you well to familiarize yourself with different manufacturers’ offerings by reviewing their catalogs. These also serve as excellent research tools if a customer requests a lock function that you aren’t immediately familiar with.  

Universal Function Mortise Locks

Best 45H “Universal Function” Mortise Lock. Screw positions (labeled 1-5) allow the lock’s function to be changed in the field.


BEST, Sargent, and Schlage offer multi-function/universal mortise locks. These mortise lock bodies are capable of multiple, different functions with a single lock body. Changes to the lock body, such as screws in BEST’s case as seen above, result in changes to the function. Changing of these functions can potentially require you to add, remove, or swap existing trim and/or components. For example, transforming a passage function mortise lock to a storeroom function mortise lock requires a mortise cylinder. It’s important to understand these changes when quoting to change the function of mortise locks so that you and your customer don’t incur additional costs during the job and/or potentially leave unfilled holes in the door.

Additional catalogs, instruction sheets, parts lists, sell sheets, and templates can be found in the 10 Line documents section on the Sargent website.

Overview

The Sargent 10 Line is one of two Grade 1 cylindrical leversets offered by Sargent, the other being the 11 Line/T-Zone. The 10 Line is offered in 6 lever styles (B, G, J, L, P, and Y) and two rose designs (G and L). There are 19 different functions available for the 10 Line as well as a fail safe and fail secure electrified/electromechanical function. The 10 Line comes standard with C10-1 conventional cylinders but they can be ordered with Signature, XC, Degree DG1, DG2, and DG3 cylinders. Additionally, they can be ordered prepped for a 6300 LFIC as well as SFIC.

History

10 Line Exploded View (Manufactured After 2/17/04)


The Sargent 10 Line has seen two different versions, the latter of the two being utilized on locks manufactured after February 17, 2004. There are a number of differences between both versions as it relates to the overall design but two can be easily observed by removing just the outside scalp and lever handle:

  1. The newest version of the 10 Line utilizes spacer bushings (#11 in the exploded view) under each lever handle. The older version does not.
  2. The newest version of the 10 Line utilizes a press-fit scalp (#3 in the exploded view). The older version utilized a scalp that was pushed against the rose assembly and then rotated, thus locking it into place.

Scalp on older Sargent 10 Line


Furthermore, the newest version of the 10 Line is the only cylindrical leverset currently produced by Sargent that utilizes spacer bushings.
Finally, one of the neat features of the 10 Line, both versions, is that the through-bolt studs can have their position changed to match existing preps. For example, if you are installing a 10 Line in a door that was previously prepped for Corbin Russwin CL3300 (2 & 8 o’clock hole positions) or a Marks 195 (6 and 12 o’clock hole positions) a simple reconfiguration of said studs would allow the 10 Line to be installed without additional drilling. For the newest version, this process is described step 2A of the installation instructions. For the older version, this process is described in step 2 below.

Installation

The installation instructions for the newest version of the 10 Line are linked above. I could not find the installation instructions for the older version of the 10 Line on the Sargent website but there are still plenty in use and it might be beneficial for you to know the process. With that said, here is the installation process for the older versions:

1. Install latch in door.


2. Install through-bolt studs in appropriate holes to match prep.


3. Install lock body in door.


One quick note here, and this is something that I often see overlooked. In this instance I’m installing a passage function lock. I cannot tell you how often I see the mounting screws installed on the wrong side of the door for passage function locks. Passage function cylindrical leversets allow free ingress and egress. Therefore, it matters not if someone has access to the mounting screws. Place the mounting screws on the outside of the door so that, in the event the lock failed and/or there was an entrapment, you or the next person will be able to disassemble the lock from the outside of the door.

4. Install support plate.


5. Install hex nut.


The spacer hex nut threads directly onto the lock chassis and affixes it with the support plate. Start by hand threading the nut and then tightening it fully with a pair of Channel locks, or similar tool. They do make a spacer wrench (originally included with the lock) if you are able to find one.

6. Install inside rose assembly.


8. Install screws to secure inside rose assembly to the lock body.


There are 2 inside screws and they are #10-32 x 1 3/4″ each.

9. Install support screws.


Like nearly all Grade 1 cylindrical leversets, the inside rose assembly contains holes not utilized by the through-bolts that can be used to affix the inside rose assembly to the door itself and provide a stronger, more reliable installation.

10. Install inside rose scalp.


The inside rose scalp contains notches that mate with the inside rose assembly and allow you insert it flush against the door. Once flush, rotate the inside rose scalp clockwise to lock it into place.

11. Install inside lever.

Patents That Shaped American Locksmithing, Part 3: Walter R. Schlage's Cylindrical Lock

The gallery was not found!
Patent Number: 1,674,841 (Google Patents)
Filing Date: August 20, 1923
Issue Date: June 26, 1928
Inventor(s): Walter R. Schlage
Background
I would personally consider the 19th century as the “golden era” of lock innovation and discovery. The first half of the century, or at least a large portion of it depending on who is defining it, was part of the Industrial Revolution. New manufacturing processes and factories allowed for innovation and inventions never before seen. Men like John Wilkinson and Henry Maudslay helped usher in a new wave of development in machining and tooling. Among the Wilkinson’s and Maudslay’s of the world were the Blake brothers of New Haven, Connecticut. On December 31, 1833, they received a patent for their “escutcheon latch” which was, for all intents and purposes, the forerunner of the modern cylindrical lock.
The “escutcheon latch” was a radical departure from the norm of the time: the mortise lock. Rather than a lock case operated by a key and/or auxiliary trim, the escutcheon latch contained a latch and knob trim that were much, much smaller and utilized a door prep that paled in comparison to it’s mortise counterparts. To quote lock historian Thomas F. Hennessey, “This type lock was almost one hundred years ahead of its time as it did not become popular in the lock industry until the 1930s.” While the “escutcheon latch” never caught up, other inventors sought to create their own version of what could compete with and perhaps even replace the mortise lock. Other early patents related to modern cylindrical and tubular locks included:

In 1923, however, Walter Reinhold Schlage, a German who immigrated to the United States and created his own lock company, filed a patent for what we now call the cylindrical lock. Walter’s version utilized knob trim, and relied on a just two small holes in the door to install. This patent wasn’t the first or last Walter received for a version of a cylindrical lock, however. Others included:


Aftermath
With his design, Walter was able to successfully challenge the mortise lock, the de facto standard for doors, exterior and interior, found in American residences. Schlage’s invention allowed doors to be fitted with a lock at a fraction of the time and cost of mortise locks. Furthermore, largely due to his companies’ existing manufacturing capabilities – which were able to manufacturer 20,000 locks a month by 1925, Walter was able to mass produce the lock. The lock became a hit and locks in America would never be the same. The cylindrical lock still remains the overwhelming standard in American residential construction. It also has a very large market share in commercial construction as well.
Over the course of his life, Walter Schlage was issued an astounding 250 patents related to locks. In 1946, Walter died but his companies continued to flourish. Schlage continued to expand and purchased other lock and door hardware companies, such as LCN. In 1974, Schlage was acquired by Ingersoll and Rand and in turn acquired new manufacturing facilities in New Zealand (1975) and Colorado (1976). Schlage would relocate it’s administrative offices to Colorado in 1997 while keeping it’s Technical Services and Customer Services divisions in San Francisco. In 2013, Schlage, along with 23 other global brands, were acquired by Allegion, where they still operate to this day.

Library Update: ANSI/BHMA Lock Function Reference Chart

We’ve just added a reference chart (direct link here) to the Library which contains function numbers, common names, and descriptions of the most popular ANSI/BHMA mortise, bored (cylindrical), interconnected, deadbolt, deadlatch, and deadlock functions. It’s laid out in a way that we think is streamlined for locksmiths who may have not fully committed these functions to memory.
If, for example, you wanted to decipher the function of a lock in hand OR you wanted to specify a function number based on the characteristics of the lock, you can quickly narrow it down by utilizing this sheet. This, we believe, is far more advantageous than the current method of reading multiple function descriptions via manufacturer’s literature.
The derived information should be compared to the manufacturer’s literature as final confirmation prior to ordering their specific lock.
 

Library Update: Cylindrical Leverset Manufacturers Cross-Reference

We’ve recently added a cross-reference PDF to the Cylindrical and Tubular Resources page  (direct link here) that provides a list currently produced of Grade 1, 2, and 3 cylindrical leversets offered by 10 popular manufacturers. These manufacturers include: Arrow, BEST, Cal-Royal, Corbin Russwin, DORMA, Falcon, General Lock, Hager, LSDA, Marshall Best, Sargent, Schlage, Tell, and Yale.
This cross-reference can be sourced to easily identify comparable cylindrical leversets series or to source and compare series unfamiliar to you.
