Sargent 82-2121 – Frequently Asked Questions

1) What is the Sargent 82-2121 fire stop assembly actually used for?
The 82-2121 is a fire stop mounting assembly for Sargent mechanical locks. It is a replacement part, not a complete lock, and it supplies the mounting hardware that ties the lock components together in a fire-rated door application. If your Sargent lock is being rebuilt or a fire stop assembly has been lost or damaged during service, this is the part that restores it.
2) Does the Sargent 82-2121 work with any lock function, or do I have to order per function?
One part covers the range. The 82-2121 is specified for all functions, so you do not need to match it to a storeroom, classroom, office, or passage lock separately when ordering for a Sargent mechanical lock. That matters for MRO stockrooms standardizing a shelf part across a mixed set of openings.
3) Is the Sargent 82-2121 a genuine Sargent part or an aftermarket copy?
It is an authentic Sargent lock part, built to original equipment specification, which is why it drops into compatible Sargent lock systems without modification. On fire-rated openings that distinction matters: locksmiths and facility inspectors generally want OEM components in the assembly rather than a generic substitute.
4) Is the Sargent 82-2121 a complete lock or do I still need the lockset?
It is a component, not a lockset. You get the mounting assembly, which supplies the structural elements for mounting the lock hardware. The lock chassis, trim, cylinder, and strike are separate items. Order it when you already have the Sargent lock in the door and need the fire stop assembly replaced.
5) How many options do I have to pick when ordering the Sargent 82-2121?
None. The 82-2121 ships as a single configuration, with no handing, finish, or size choice to specify. You order the part number and that is the whole decision.
