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.


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.


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.
