Sargent 10-3157 – Frequently Asked Questions

1) What exactly is the Sargent 10-3157, and is it a complete lock or just the case?
The 10-3157 is a lockbody assembly only, the mortise lock case for Sargent 10-Line mortise locks. It contains the core mechanical works of the lock, not the trim, levers, roses, cylinder, or strike. If you are rebuilding a 10-Line opening you reuse the existing trim and cylinder and drop this case into the mortise pocket.
2) Will the Sargent 10-3157 lock case fit any mortise lock, or only Sargent?
Only Sargent 10-Line mortise locks. It is a genuine Sargent part built to the original assembly specification for that series, so it drops into an existing 10-Line installation. It is not a universal mortise case, and there is no stated fit to any other manufacturer's mortise prep.
3) What is the option number I have to pick when ordering the Sargent 10-3157 lock case?
Two option numbers are offered on the 10-3157: 04 and 37. The case is factory configured with the SF option, and the option number you choose has to match the configuration of the lockset you are servicing, so pull the number off the existing lock or its order record before you buy.
4) My Sargent mortise lock is failing but the levers and cylinder are fine. Do I replace the whole lockset?
No need on a 10-Line. Swapping just the lockbody assembly restores the mechanical function while you keep the existing trim and cylinder, which also keeps the opening keyed the way it already is. That is the point of stocking the case as a separate replacement part: less downtime and no re-keying on a service call.
5) Is this Sargent lock case rated for commercial traffic, or is it a residential part?
Commercial. The 10-3157 is a commercial door hardware part, built to the same specification as the original assembly, and 10-Line mortise locks are used in offices, schools, healthcare buildings, retail, government facilities, warehouses and multi-tenant residential.
6) I manage a building with dozens of Sargent 10-Line doors. Can I stock one 10-3157 for all of them?
Not one part number for all of them. The 10-Line case is configured by option, and the 10-3157 comes as option 04 or option 37, so what you stock has to match the configuration on the doors you are covering. Survey a few openings first; if your doors were ordered as a single spec you may only need one of the two.
