Start with the lock function number
Most Sargent 8200 parts are chosen by the lock's function, the two digits after 82 in the model number, for example 8204 storeroom or 8237 classroom. The function decides which front plate, trim pack and indicator fit. Find it on the original order, on the lock face or in the Sargent 8200 mortise lock parts manual (PDF) we host on our product pages.

Trim packs: change the look or the lever
A TR-82 trim pack holds the lever and rose or escutcheon for one function, so you can change the trim or replace damaged levers on an existing 8200 body. The code after the function names the trim: LN, L and O are roses, LE1, LE2, LW1, LS and WT are escutcheons, and the last letter is the lever design (A, B, E, F, J, L, P or W). For example, the TR-8237 LNB is a classroom trim pack with LN rose and B lever. Match the function of the trim pack to the lock body.
Strikes and lip length
Choose a curved lip strike by the lip length needed to protect the frame and guide the latch, measured from the strike center to the edge of the lip. The catalog lists 8200 curved lip strikes with lips of 1-1/8" (82-0109), 1-1/4" (82-0110), 1-3/8" (82-0111), 1-5/8" (82-0112), 2-1/8" (82-0114), 2-3/8" (82-0115) and 2-7/8" (82-0117). The 78-0034 is a deadlock strike with no lip, and the 77-1141 is the wrought strike box.
Outside front plates by function
The outside front plate is the faceplate on the edge of the lock, and it is cut for the function's latch and bolt. Sargent lists one plate per group of functions: for example 82-0080 for functions 15 and 65, 82-0084 for 40, 41, 50, 51 and 52, 82-0085 for 55, 82-0086 for 45 to 48, 82-0087 for 43 and 82-0088 for 89 to 92. The full list of functions for each plate is on the listing.
Indicators: vacant/occupied and lockdown status
An indicator shows the lock status from outside, which is useful on restrooms, conference rooms and classrooms. The 185P is an 8200 occupancy indicator part, the 185S-2 is a secure indicator rose for 7800/8200 locks on 1-3/4" doors, and the SA190 to SA198 indicators for sectional trim are listed in Vacant/Occupied, Unlocked/Locked and icons-only versions (V-codes on each listing).

Frequently Asked Questions
Where can I find the Sargent 8200 mortise lock manual?
We host the Sargent 8200 mortise lock parts manual and the 7800/8200 catalog as PDFs on our product pages and link them on this page. The parts manual shows exploded diagrams with part numbers, and the catalog shows functions and trim options.
Do Sargent 7800 parts fit the 8200?
Some parts are shared and are listed for both, such as the 185S-2 secure indicator rose for 7800/8200 locks. Other parts are specific to one series. Check the "for use with" information on each listing, or send us the lock model to confirm.
Can I change the function of a Sargent 8200 lock?
In most cases the function is built into the lock body, so changing from one function to another means replacing the body and, depending on the function, the outside front plate, cylinders or trim. Match the new function number to the lock body before you order, and keep the existing trim if it fits the new function.
