Sargent TR-8224 LNF 20D – Frequently Asked Questions

1) Does the Sargent TR-8224 LNF 20D include the mortise lock body, or just the trim?
Trim only. The TR-8224 LNF 20D is a trim pack for the Sargent 8200 Series mortise lock platform: it supplies the interior and exterior trim components to complete or upgrade an existing 8200 Series mortise lock assembly. The lock case itself is separate, and so is the cylinder. If your door has no 8200 case in it already, you need the complete mortise lock, not this pack.
2) What does Sargent function 20D, Room Door, actually do on the door?
Room Door function (20D) is a single cylinder with deadbolt arrangement, keyed from the outside for room and office access control. You get lever operation plus a separately thrown deadbolt for added security on the opening. It is the configuration commonly used on interior room and office doors in commercial buildings rather than on corridor or entry openings.
3) Will the TR-8224 trim fit a Sargent 8200 mortise lock that currently has a different lever and rose?
Yes, within the 8200 platform. The TR-8224 is built to the 8200 Series trim mounting, so it swaps onto a compatible 8200 mortise lock. What changes is the look and the function set: you are moving to the LN round rose with the F lever in Dark Bronze Painted, and to the 20D Room Door arrangement with single cylinder and deadbolt. Mixing trim across a different manufacturer's mortise case is not something this part is made for.
4) Do I need to order a cylinder separately with the TR-8224 LNF 20D trim pack?
Plan on it. The 20D Room Door function is a single cylinder with deadbolt arrangement, so the opening needs a mortise cylinder keyed into your system to operate it. The trim pack covers the rose, lever and trim components; the keying decision (keyway, keying to an existing master system, cylinder length and cam) is made when you order the cylinder.
5) Is the Corbin Russwin 483F80 lever a substitute for the Sargent TR-8224 LNF 20D trim pack?
No. The Sargent TR-8224 LNF 20D is a complete mortise lock trim pack for the Sargent 8200 Series, supplying both interior and exterior trim in a Room Door Function configuration with single cylinder and deadbolt, LN round rose and F lever. The Corbin Russwin 483F80 is an outside lever and spindle only, built for the Corbin Russwin ML2000 Series and listed for a 1-3/4 inch thick door, with a Corridor/Dormitory function. Different lock platform and a partial trim component rather than a full pack, so the two are not interchangeable on the same door.
6) Is the F lever on this Sargent trim suitable for ADA lever hardware requirements?
The F lever is a lever-style handle compatible with ADA-accessible hardware configurations commonly specified in commercial construction, which is why lever trim rather than a knob gets called out on most commercial drawings. Sargent describes it as a professional-grade lever form for that use.
7) What finish is 20D on Sargent trim, and will it match my other dark bronze door hardware?
20D is Dark Bronze Painted, listed on the finish option as 690 Dark Bronze. It is a painted dark bronze rather than an oil-rubbed or living finish, so it holds a consistent color across a run of openings. If the rest of your building is on 690 dark bronze Sargent hardware, this matches that program; if your existing trim is an oxidized or plated bronze, expect a visible difference in tone and sheen.
8) I only need to replace a broken outside lever on a mortise lock, not the whole trim set. What should I look at?
If the door carries a Corbin Russwin ML2000 Series mortise lock, the 483F80 is sold as just the outside lever and spindle for a 1-3/4 inch thick door, so you replace the damaged piece alone. The Sargent TR-8224 LNF 20D is the fuller approach: a complete trim pack for the Sargent 8200 Series mortise lock, providing the interior and exterior trim components needed to complete or upgrade the assembly. Match the choice to the lock body already in the door.
9) For standardizing mortise lock trim across a facility, how do the Sargent TR-8224 LNF 20D and Corbin Russwin 483F80 differ?
They belong to separate mortise platforms. The Sargent TR-8224 LNF 20D is a commercial trim pack for the Sargent 8200 Series in Dark Bronze Painted (20D) with an LN round rose and F lever, intended for commercial and institutional openings. The Corbin Russwin 483F80 is a Grade 1 ML2000 Series outside lever and spindle in the LW design for a 1-3/4 inch thick door. Standardizing means picking the lock series first, since the trim follows the series rather than crossing between them.
10) Is this Sargent trim rated for commercial traffic or is it a residential part?
Commercial. The TR-8224 LNF 20D is classified as commercial door hardware and is a genuine Sargent 8200 Series part, used on office buildings, schools, healthcare facilities, hotels, multi-tenant residential, and government buildings. It is not a light-duty residential trim.
11) Can I use the TR-8224 LNF trim to standardize the look across a floor of rooms?
That is the usual reason to buy it. The LN round rose with the F lever is a single, repeatable trim profile, and the 690 dark bronze finish is a painted finish that holds consistent color unit to unit. Keeping every room door on the same 8200 Series case with the same 20D Room Door function also means one keying scheme and one spare-parts line for the building, which is what most facility teams are after.
