Sargent 82-4577 – Frequently Asked Questions

1) What is the Sargent 82-4577 part used for?
The 82-4577 is an inside adapter and plate assembly for Sargent mechanical locks. It sits on the inside of the lock and carries the trim, and it is sold as a replacement part for servicing an existing Sargent lock rather than as a complete lockset. If you are rebuilding a lock and the inside adapter or plate is damaged, this is the piece that restores it.
2) Which Sargent lock functions does the 82-4577 adapter and plate work with?
It covers six functions: CO, CR, LN, O, TO and TR. Check the function code stamped on your lock or on the original hardware schedule before ordering. If your opening uses a function outside that list, the 82-4577 is not the adapter for it.
3) Does ordering the Sargent 82-4577 give me a complete lockset?
No. The 82-4577 is the inside adapter and plate assembly only. Levers, knobs, cylinders, the lock chassis and the strike are separate. Order it when you are repairing a lock that is otherwise serviceable; if the chassis itself has failed you need a full lock, not this part.
4) Is the 82-4577 rated for commercial door traffic or is it a residential part?
Commercial. Sargent lists the 82-4577 as commercial-grade hardware, and it is the part specified for service work in offices, schools, hospitals, government buildings, retail, multi-tenant residential and industrial facilities. It is not a light-duty residential component.
5) Does the Sargent 82-4577 come in different sizes or finishes?
It is a single part number with no size or finish options to select. Ordering 82-4577 gets you the one configuration Sargent builds for the CO, CR, LN, O, TO and TR functions.
