Don-Jo BF-178-PC – Frequently Asked Questions

1) Will a Don-Jo BF-178 filler plate cover the hole left after removing a cylindrical lockset?
Only if the hole is the smaller 1-7/8 inch prep. The BF-178 is sized at 1-7/8 inch diameter, so it covers a 1-7/8 inch bore and nothing larger. Most modern cylindrical locksets are bored 2-1/8 inch, and a 1-7/8 inch plate will drop straight through that hole. Older prep, deadbolt and small-bore holes at 1-7/8 inch are what this one is for. Measure the hole across before ordering.
2) Does the Don-Jo BF-178 come as a single piece or do I need two for a through hole?
A bore that goes through the door shows on both faces, so a full patch takes two plates, one per side. Order in pairs when you are covering a through bore and want the door to look finished from the corridor and the room. The BF-178 is stocked in a shelf pack of 10, which covers five doors done both sides.
3) What finishes does the Don-Jo BF-178 hole filler plate come in?
Five: brass plated (BP), chrome plated (CP), Duronodic brown coated (DU), prime coated (PC) and silver coated (SL). If you are patching a door that is going to be repainted, prime coated is the one to take, since it is meant to be finished on site. On a door with existing hardware, match the plating to the lock trim already there rather than the door color.
4) Is the BF-178 filler plate steel or plastic, and will it hold up on a high traffic door?
Steel, at 16 gauge (.060). That is a rigid plate rather than a thin snap-in cover, which is why it is used on commercial openings that take abuse: corridor doors, warehouse doors, school and healthcare doors. The plated and coated finishes are surface treatments over that steel body.
5) I pulled a lock off a door and want to reuse the door. Is a filler plate the right fix or do I need a wrap around?
Two different jobs. A hole filler plate like the BF-178 covers a single unused bore hole and leaves it flat and finished. A wrap around plate is what you want when the door face itself is damaged or split around the prep, or when you are reinforcing a prep you intend to keep using hardware in. If the door is sound and the hole is simply orphaned at 1-7/8 inch, the filler plate is the cheaper, simpler patch.
6) Can I use a BF-178 filler plate on a hollow metal frame, not just the door?
Yes. The plate is used on doors and frames alike, covering old strike or cylinder prep in hollow metal frames the same way it covers a bore in the door face. What matters is the hole diameter, 1-7/8 inch, not which part of the opening it sits on.
7) I manage a building and need the same patch on a lot of doors. Is the BF-178 sold in bulk?
It ships in a shelf pack of 10, which is the quantity that suits a fleet of openings being cycled through a hardware change rather than a one door repair. Take a single finish across the building so the patched doors read the same, and remember a through bore needs a plate on each face.
