Don-Jo BF-135-PC – Frequently Asked Questions

1) I am converting a knob-prepped door to a push/pull or card reader. Do I need one BF-135 or two?
Two, one per face, if the bore goes all the way through the door, which it does on a standard cross bore. The BF-135 is a 3-3/4 inch cover plate, not a plug, so it hides the opening on the side it is mounted to and nothing more. Order in pairs per door and remember it ships in shelf packs of 10, which covers five doors.
2) Will a 3-3/4 inch hole filler plate cover an old mortise lock cutout?
No. The BF-135 is a round 3-3/4 inch plate sized for a bored hole. A mortise pocket is a tall rectangular cutout in the door edge with a face prep several inches long, and a round plate this size will not reach it. For that job you want a rectangular mortise lock filler or a wrap-around style plate, not this one.
3) What finishes does the Don-Jo BF-135 hole filler plate come in?
Five: brass plated, chrome plated, duronodic brown, prime coated, and silver coated. Prime coated is the one to order when the door is getting painted, since it takes finish paint directly and lets the plate disappear into the door color. Brass and chrome plated are the picks for matching existing lever roses and escutcheons on the rest of the openings.
4) Is 16 gauge steel heavy enough for a filler plate on a high traffic commercial door?
16 gauge (.060) steel is the commercial weight for this part, and it is rated commercial rather than residential. It resists the denting and oil-canning a thin plate picks up in a corridor or stairwell, and it stays flat against the door face instead of bowing away from the bore edge over time.
5) Can the Don-Jo BF-135 be used on a hollow metal door as well as wood?
Yes, on either. It is a surface applied steel plate that covers the bore from the door face, so the door material underneath does not change how it sits. Steel construction is what makes it suited to hollow metal openings in offices, schools, healthcare and warehouse buildings where a plastic or thin plate would not hold up.
6) Does the BF-135 come as a single plate or do I have to buy a box?
It comes in a shelf pack of 10 plates. That is the practical quantity for a contractor or facility running a hardware changeout across a floor of doors, and at two per door it covers five openings.
