Don-Jo FL-212NM-BP – Frequently Asked Questions

1) What does the Don-Jo FL-212NM security strike actually do on a commercial door?
The FL-212NM is a latch protection and frame reinforcement plate, not a lock or a latch. It mounts on the frame side at the latch, covering the strike area of the jamb so a pry bar or a spread frame can't get at the latch. It measures 12 inches by 1-3/8 inches with a single latch hole, and it's made of 13-gauge (.095) ferrous material.
2) Will the Don-Jo FL-212NM work on a door with two latches, like a lock plus a deadbolt?
No. The FL-212NM is drilled with one latch hole, so it covers a single latch point only. If the opening has a latch and a separate deadbolt, one filler plate can't serve both unless the second hole is field-prepped, and that isn't how the part ships. For those openings look at a filler or wrap plate cut for two holes.
3) Is the Detex 92 strike kit an equivalent to the Don-Jo FL-212NM security strike?
They solve different problems. The Don-Jo FL-212NM is a security strike measuring 12 inches high by 1-3/8 inches wide, made from 13-gauge (.095) ferrous material with a single latch hole, so it reinforces a run of frame around one latch point on a commercial opening. The Detex 92 Strike Kit, part of the Detex 90 Strike Series, is a double door strike kit supplied with tamper resistant fasteners, so it is aimed at the meeting stile of a pair of doors rather than a single-latch frame reinforcement. If the opening is a single door and the goal is frame reinforcement behind the latch, the FL-212NM is the one that matches; for a double door application handled as a kit, the Detex 92 addresses that configuration.
4) What should I use instead of a Don-Jo FL-212NM when the strike has to land on a pipe or round post rather than a flat frame?
The Don-Jo FL-212NM is a flat security strike 12 inches high and 1-3/8 inches wide in 13-gauge (.095) ferrous material, dimensioned to sit against a conventional door frame face. On a pipe or round post there is no flat face for it to bear on. The Trimco 1260P, from the 1260 Series, is a pipe adapter strike supplied as the strike only, which is the part made for adapting a latch strike to a pipe mounting condition. Confirm the latch hardware and post condition before ordering either one.
5) Is 13-gauge steel heavy enough for a high-traffic commercial entry?
13-gauge works out to .095 inch of ferrous stock, which is substantially heavier than the light stamped strikes that come packed with most locksets. That thickness is why the FL-212NM is specified as a commercial part rather than a residential one, and it's the reason it holds up on schools, healthcare corridors, and multi-tenant entries where doors get abused.
6) Difference between the Don-Jo FL-212NM and a Trimco 1260P pipe adapter strike?
They solve unrelated problems. The FL-212NM is a 12 inch ferrous plate that reinforces a standard frame jamb at the latch. The Trimco 1260P is a pipe adapter strike, meant for a round pipe or tube frame where a flat plate has nothing to sit against. Pick by what the latch is striking into: flat jamb, use the Don-Jo; pipe, use the adapter.
7) Can I use the Don-Jo FL-212NM to cover up damage where an old strike was pried out?
That's a common use for it. At 12 inches long by 1-3/8 inches wide, the plate spans well above and below the original strike cutout, so it hides torn or deformed jamb metal and puts fresh .095 stock across the latch point. You'll still need to line up its single latch hole with where the existing latch throws.
8) I need a strike for a pair of doors with security fasteners - does the Don-Jo FL-212NM cover that, or do I need a kit?
The FL-212NM is a single security strike with one latch hole, sold in shelf packs of 10 and offered in brass plated and silver coated finishes, so it is bought and installed one frame location at a time. It does not come as a double door assembly and does not include tamper resistant fasteners. The Detex 92 Strike Kit is the double door strike kit and is furnished with tamper resistant fasteners, which is what a paired opening specified for security fasteners is asking for. For a facility standardizing single-door openings on heavy-gauge frame reinforcement, the FL-212NM is the piece that repeats across doors.
9) What finishes does the Don-Jo FL-212NM security strike come in?
Two: BP (brass plated) and SL (silver coated). SL is the one that disappears against a painted or galvanized hollow metal frame; BP is for openings where the rest of the trim is brass-toned. Since the plate is ferrous under the coating, either finish can also be painted to match the frame if neither is a match.
10) How is the Don-Jo FL-212NM sold, single piece or in a box?
It's supplied in shelf packs of 10. That suits the way this part is usually bought, which is a run of openings at once rather than one door, and it's why contractors and facility maintenance groups stock it.
11) Can I standardize on one strike reinforcement across a whole building?
Where the openings share a single latch point and a jamb that accepts a 1-3/8 inch wide plate, yes. The FL-212NM in SL is the practical fleet choice for hollow metal frames, and buying in packs of 10 keeps a spare stock on the shelf. Openings with a separate deadbolt above the lock need a different, two-hole plate.
12) Does ordering a Trimco 1260P get me a complete strike assembly the way a Don-Jo FL-212NM does?
The Trimco 1260P is catalogued as strike only, so it is the strike component of the 1260 Series pipe adapter arrangement and the rest of the mounting condition has to already be in place. The Don-Jo FL-212NM is a one-piece security strike, 12 inches by 1-3/8 inches in 13-gauge (.095) ferrous material with a single latch hole, supplied in shelf packs of 10, so each unit is the whole part that goes on the frame. Buyers stocking replacements for single commercial openings usually want the self-contained piece.
