Sargent 10-0287 – Frequently Asked Questions

1) What Sargent locks does the 10-0287 tailpiece fit?
The Sargent 10-0287 tailpiece is built for the 54 function platform, and fits 10L and 7L series lock functions. If the lock you are servicing is a different Sargent function, this is not the right tailpiece - the tailpiece length and engagement are function specific.
2) My Sargent mortise lock turns with the key but the latch does not retract - is the tailpiece the problem?
That is the classic symptom of a worn, bent, or wrong-length tailpiece. The tailpiece is the mechanical link between the cylinder plug and the lock body, and it is what carries key rotation into the latch or bolt. If the key turns freely and nothing moves inside the case, pull the cylinder and inspect the tailpiece. On a 54 function 10L or 7L lock with a 7-pin cylinder, the 10-0287 is the replacement.
3) Does the Sargent 10-0287 come with a cylinder?
No. The 10-0287 is the tailpiece only, a replacement part for the cylinder-to-lockbody connection. If you are also replacing the cylinder, order a 7-pin Sargent cylinder in your keyway separately, plus the cylinder retaining screws if yours are damaged.
4) Do I have to modify the lock to install the Sargent 10-0287 tailpiece?
No modification. It is a drop-in replacement built to original equipment specification, so it restores cylinder function in the existing hardware without drilling or filing. For a property manager or in-house maintenance tech, that means the door comes back into service on the same prep.
5) Is the Sargent 10-0287 a genuine OEM part or an aftermarket copy?
It is a genuine Sargent lock part, made to original equipment specifications rather than an aftermarket reproduction. That matters on institutional work where the specification calls for factory parts to keep the hardware assembly intact.
6) Is this tailpiece rated for high-traffic commercial doors or is it a residential part?
Commercial. The 10-0287 is designated for commercial use and is the service part for Sargent mechanical locks in offices, schools, healthcare, government buildings, retail, warehouses, and multi-tenant residential. It is not a residential-grade component.
7) I am standardizing keying across a building on Sargent 7-pin cylinders - does the tailpiece affect key control?
The tailpiece itself carries no keying, but it has to match the pin count of the cylinder system you standardize on. The 10-0287 is the 7-pin version, which is what you use when the facility runs 7-pin cylinders for tighter key control on 54 function 10L and 7L locks. Keying and keyway are specified on the cylinder, not here.
