Hager 336B USP – Frequently Asked Questions

1) What is an 86 prep filler plate actually used for on a door?
An 86 prep is the mortise-lock cutout in the edge of a door. When a mortise lock is removed, or the door was prepped for one that is not being installed, the 336B filler plate covers that edge cutout so the door edge reads flush and finished. It is a cover plate, not a lock and not a strike.
2) What size is the Hager 336B filler plate, and will it cover a standard mortise lock edge cutout?
The 336B measures 1-1/4 by 8 inches (32 mm x 203 mm), which is the standard face size of an 86 mortise prep in a commercial door edge. Plate thickness is .2 inch (5.1 mm), in 0.18 inch gauge steel. Measure your existing cutout before ordering: if the prep in your door is wider or longer than 1-1/4 by 8, this plate will not cover it.
3) Does the Hager 336B come painted, or do I have to finish it?
It ships in USP, a primed coat paint finish, on primed steel. That is a paint-ready base, not a final finish, so plan on painting it to match the door or the surrounding trim. If you need a plated finish out of the box to match lever trim, this is not the part for that.
4) I have a whole building of doors with abandoned mortise preps. How does the Hager 336B sell for that kind of job?
It is packed 25 to a box and 250 to a case, which suits exactly that situation: a property manager or MRO buyer covering abandoned 86 preps across a floor or a building rather than fixing one door. Each plate covers one door edge cutout.
5) Do screws come with the Hager 336B edge filler plate?
Fasteners are chosen to suit the door material rather than supplied as a set with the plate. The install is straightforward: set the plate over the edge prep, line it up with the existing hardware mounting points, confirm it sits flush, then fasten and paint. Budget separately for screws appropriate to a hollow metal or wood door.
6) Will the 336B filler plate sit flush in the door edge or stand proud of it?
At .2 inch (5.1 mm) thick it sits on the face of the edge prep, so it stands slightly proud unless the prep is relieved for it. On a door that already had a mortise lock face plate in the same pocket, it drops into that recess. Check the depth of the existing pocket before you cut anything.
7) Is the 336B filler plate rated for commercial traffic or is it a residential part?
Hager lists the 336B as commercial. The 0.18 inch gauge primed steel body is built for commercial openings, offices, schools, healthcare, retail, warehouses, and multi-tenant residential, rather than light residential use.
