Don-Jo FBR-B – Frequently Asked Questions

1) How do I cover the flush bolt cutout in a door edge after removing the flush bolt?
A flush bolt filler plate is the part for that. The Don-Jo FBR B covers the mortised flush bolt prep on the door edge, measuring 5-7/8 x 1-1/4 inches in 16 gauge (.060) steel. You mount it over the existing cutout so the edge reads as a finished face instead of an open pocket. It does not restore any latching function, it is purely concealment of the prep left behind.
2) Will the Don-Jo FBR B filler plate cover my flush bolt cutout, or do I need to measure first?
Measure the cutout before you order. The FBR B gives you 5-7/8 inches of length and 1-1/4 inches of width of coverage, so the mortise in your door edge has to fall inside that footprint. Flush bolt preps vary by the bolt that was originally installed, and a longer or wider pocket than 5-7/8 x 1-1/4 will show at the ends or along the sides.
3) Does a flush bolt filler plate replace the flush bolt, or do I still need a bolt to secure the inactive leaf?
It replaces nothing functionally. The FBR B is a blank cover for the mortise, with no bolt, no rod, and no latching. If the inactive leaf of your pair still needs to be held top and bottom, you need a flush bolt or another means of securing that leaf, and the filler plate is what you use only once you have decided that leaf will no longer be bolted.
4) Is a 1-1/4 inch wide filler plate going to fit the edge of a standard commercial door?
1-1/4 inches of width sits comfortably on the edge of a 1-3/4 inch door, which is the standard commercial thickness, leaving material on both sides of the plate. On a 1-3/8 inch door, common on older interior openings, the plate still fits the edge but with less margin, so check where the original flush bolt mortise sits relative to the door faces.
5) Is 16 gauge steel heavy enough for a filler plate on a high-traffic door?
16 gauge works out to .060 inch thick steel, which is the same range of material used for commercial door edge trim, and the FBR B is rated for commercial applications. On a heavily used opening in a school, hospital corridor, or warehouse, that thickness holds its shape against carts and kick traffic rather than dishing in the way thin sheet does.
6) What is the difference between a flush bolt filler plate and a wrap around plate or lock filler plate?
They cover different preps in different places. The FBR B flush bolt filler plate covers the narrow mortise in the door EDGE where a flush bolt was set, 5-7/8 x 1-1/4 inches. A lock filler plate covers an abandoned lock prep on the door FACE, and a wrap around plate wraps the edge and both faces to reinforce or hide damage around a lockset bore. If what you are covering is a cylindrical or mortise lock hole in the face of the door, this edge plate is the wrong part.
7) How many Don-Jo B filler plates come in a pack?
They come as a shelf pack of 10. For a property manager or contractor converting several pairs of doors, or standardizing the look of edges across a building after removing flush bolts, that covers ten door edges from one order rather than buying singles per opening.
8) Can I paint or finish the Don-Jo FBR B to match my door edge?
The plate is steel, so it takes primer and paint the same way a hollow metal door edge does. On a painted commercial door, the usual approach is to install, then prime and topcoat the plate along with the edge so the patch disappears.
