Sargent TR-8224 LNB 20D – Frequently Asked Questions

1) Does the Sargent TR-8224 LNB 20D include the mortise lock body, or is it trim only?
Trim only. The TR-8224 LNB 20D is a trim pack (levers, LN roses and the mounting hardware in the pack) for the Sargent 8200 Series mortise lock platform. You mount it to a compatible 8200 Series lock body, which is bought separately, along with the cylinder for the deadbolt function. If your existing 8200 body is sound and you are only replacing broken or mismatched levers and roses, this is the part you want.
2) What does the 8224 room door function actually do on the door?
Room door function, single cylinder with deadbolt. The outside lever is controlled and a deadbolt is thrown or retracted by key from the single cylinder side, so it suits interior room entry doors in commercial buildings where you want a deadbolt as well as a latch. It is not a corridor or classroom function, so if the spec on your drawing calls for something else, the 8224 trim is the wrong number.
3) Will this Sargent trim fit any 8200 Series mortise lock, or only certain functions?
The trim is configured for the 8224 function, so it pairs with an 8200 Series body set up for room door (single cylinder with deadbolt) operation. The 8200 platform is modular, but trim and body have to agree on function, cylinder count and deadbolt operation. Match the body's function number to the 8224 trim before ordering.
4) Can I use this Sargent trim pack on a Corbin Russwin ML2000 mortise lock?
No. This trim is engineered for the Sargent 8200 Series mortise platform and mounts to those bodies. Corbin Russwin ML2000 locks take ML2000 trim, such as the 483F80 LW lever and spindle. Identify the lock body in the door first, then order trim from that same family.
5) Can a Corbin Russwin 483F80 lever be used in place of the Sargent TR-8224 LNB 20D trim?
No. The Sargent TR-8224 LNB 20D is a complete mortise lock trim pack built for the Sargent 8200 Series, configured for room door function (single cylinder with deadbolt) with the LN rose and B lever in Dark Bronze Painted 20D. The Corbin Russwin 483F80 is an outside lever and spindle for the Corbin Russwin ML2000 Series in the LW lever style, sized for a 1-3/4 inch thick door, and its function is Corridor/Dormitory. Different lock platform and a single lever-and-spindle component rather than a rose-and-lever trim pack, so the two are not interchangeable.
6) What do LN and B mean in the Sargent TR-8224 LNB part number?
LN is the rose style and B is the lever design. So LNB gives you the LN round rose with the B lever profile. If the other doors on your floor already carry LN roses with B levers, this trim keeps the openings matched; if they use a different Sargent rose or lever letter, order that suffix instead so the hardware looks consistent.
7) Is 20D the same as 690 Dark Bronze on Sargent hardware?
Yes. The trim ships in Dark Bronze Painted, which Sargent designates 20D and which corresponds to the 690 Dark Bronze finish code. That is the only finish this trim pack comes in, so if your building standard is satin chrome or oil rubbed bronze you need a different finish suffix.
8) Is this trim rated for high-traffic commercial doors or is it light duty?
It is classified as commercial lock trim, built for the use levels found in offices, schools, healthcare facilities, hotels, government buildings and multi-tenant residential. It is not a residential-grade item.
