Don-Jo FB-225-PC – Frequently Asked Questions

1) What does the Don-Jo FB-225 filler plate actually cover on a door?
The FB-225 is a small steel plate that covers the cutout left behind when a flush bolt is pulled out of a door or taken out of service. It hides the mortise pocket and gives the door edge or face a finished look again instead of an open hole. It is a cover plate only, not a bolt, so it adds no latching or securing function of its own.
2) Is the FB-225 a flush bolt or a cover for one?
A cover. Don-Jo's FB-225 is a filler plate, a flat 11-gauge steel piece that goes over a flush bolt cutout. If you are looking for the working hardware that bolts an inactive leaf into the head and the floor, that is a flush bolt, an entirely different part with a rod, a lever, and strikes. Distributors and buyers cross-referencing Don-Jo's FB numbers should read the FB-225 as the filler, not the bolt.
3) I'm converting a pair of doors from flush bolts to an exit device. Is a filler plate all I need?
The FB-225 handles the cosmetic side only, it caps the 2-1/4 x 15/16 inch flush bolt cutout so the old prep does not show. It does nothing to secure the inactive leaf. Whatever is replacing the flush bolts, an exit device, a vertical rod, or a removable mullion, gets ordered separately along with its own strike and prep. Plan the filler plate as the last item on that conversion, not the substitute for it.
4) How thick is the Don-Jo FB-225 filler plate, and will it stand up to a high-traffic door?
The plate is 11-gauge steel at .119 thickness, which is heavy for a cover plate of this size and why it holds its shape on doors that get kicked, carted into, and cleaned daily. That gauge is the reason it is spec'd for commercial openings rather than a thin residential-style cover that dents.
5) What finishes does the Don-Jo FB-225 come in, and which one should I use if I'm painting the door?
Four finishes: brass plated, chrome plated, Duronodic brown coated, and prime coated. If the door is getting painted, take the prime coated version, it is meant to be finish-painted on site to match. Chrome plated is the closest match to the satin and polished chrome trim on most commercial openings, brass plated to brass hardware, and Duronodic brown for dark bronze storefront and aluminum entrance hardware.
6) Can I buy Don-Jo FB-225 filler plates in bulk for a whole building?
They come in a shelf pack of 10, which is the useful quantity if you are working through a building where flush bolts are being removed from multiple pairs. Standardizing on one finish across the job keeps the openings matching, and the four finishes are brass plated, chrome plated, Duronodic brown coated, and prime coated.
7) Will a steel filler plate rust on an exterior or wash-down door?
The FB-225 is steel, not stainless, so the finish is what protects it. Brass plated, chrome plated, and Duronodic brown coated all arrive with a factory coating on them. Prime coated is bare primer and has to be painted before it goes on anything that sees weather or wet cleaning, otherwise the primer is the only thing between the steel and the moisture.
