Sargent TR-8204 LNB 20D – Frequently Asked Questions

1) Will the Sargent TR-8204 trim fit my existing Sargent 8200 Series mortise lock?
Yes. The TR-8204 LNB is a genuine Sargent part built to drop onto Sargent 8200 Series mortise lock bodies, so it works either as a replacement on an installed lock or as the trim on a new 8200 install. It is not a universal trim, so it is not intended for other manufacturers' mortise bodies.
2) What does storeroom function mean on this Sargent lever trim, and is it right for a supply closet?
Storeroom/closet function means the outside lever stays locked at all times and is retracted only by the key; there is no thumbturn or button to leave it unlocked. That is what you want on a supply room, utility closet, or back-of-house storage door where the door should relock every time it shuts. The TR-8204 is configured for exactly that, with a single cylinder for key control from one side.
3) Can a Corbin Russwin 483F80 lever be used in place of the Sargent TR-8204 LNB trim pack?
No. The Sargent TR-8204 LNB 20D is a Sargent 8200 Series mortise lock trim pack built to fit Sargent 8200 Series mortise lock bodies, with the LN rose and B lever in Dark Bronze. The Corbin Russwin 483F80 is an ML2000 Series outside lever and spindle for a 1-3/4 inch thick door. They are trim for two different mortise lock platforms, so the 483F80 will not mount to an 8200 Series lock body.
4) I'm replacing a damaged lever on a Sargent mortise lock. Do I have to buy a whole new lock?
No. If the mortise body is still sound, swapping the trim is the cheaper fix. The TR-8204 LNB 20D covers the outside lever, rose, and the storeroom function trim for an 8200 Series body, so a bent or vandalized lever gets you back in service without pulling the lock out of the door.
5) Will 20D Dark Bronze on this Sargent trim match the rest of my building's hardware?
20D is Dark Bronze Painted, the darker architectural tone. It matches other 20D Sargent hardware. It is a painted finish rather than an oxidized bronze like 10B, so if your other doors carry a different bronze code the shade will read differently side by side. Dark Bronze is the only finish this trim pack is built in.
6) Does the TR-8204 LNB come with a cylinder?
No. It is single cylinder function trim, meaning it accepts one key cylinder on the outside, but the cylinder itself is ordered separately so you can match your building's keyway and keying. Plan on a Sargent mortise cylinder in a finish that suits the 20D trim.
7) If I only need to replace a broken outside lever, is the Sargent TR-8204 trim pack the right part?
The Sargent TR-8204 LNB 20D is a complete 8200 Series trim pack - LN rose with B lever in Dark Bronze Painted - for Sargent 8200 Series mortise bodies. If the opening is a Corbin Russwin ML2000 Series mortise lock and only the outside lever and spindle are damaged, the 483F80 outside lever and spindle for a 1-3/4 inch thick door is the component-level part for that platform.
8) What is the difference in door function between the Sargent TR-8204 trim and the Corbin Russwin 483F80?
The Sargent TR-8204 LNB 20D is configured for storeroom/closet function with single cylinder operation, so the key controls entry from one side for secured storage and utility rooms. The Corbin Russwin 483F80 is a Corridor/Dormitory function ML2000 Series lever and spindle, intended for corridor and dormitory openings. Choose by the opening's intended access behavior, not by the lever style.
9) Is the Sargent TR-8204 trim rated for commercial traffic or is it a residential part?
It's a commercial part. The TR-8204 LNB is classified as commercial lock trim within the Sargent 8200 Series line, which is the mortise family used in schools, healthcare, government buildings, and warehouse interiors. It isn't intended for light residential duty.
10) What does the B in TR-8204 LNB mean?
LN is the rose style and B is the lever style. So LNB gives you the round LN rose paired with the Sargent B lever, a straight commercial lever shape. If the other doors on your floor carry a different Sargent lever letter, the grip profile won't match even though the function is the same.
