Don-Jo FL-212N6-SL – Frequently Asked Questions

1) Will the Don-Jo FL-212N6 security strike cover the old strike cutout on my commercial door frame?
The FL-212N6 is a 12 inch tall by 1-3/8 inch wide filler-style security strike, so it runs well past a standard strike cutout and covers the mangled or oversized prep left behind after a pry attempt or a hardware change. The 1-3/8 inch width is sized to a standard commercial frame face prep. Measure your frame face first: if the flat area is narrower than 1-3/8 inches, the plate will not sit flush.
2) Why does the Don-Jo FL-212N6 have two latch holes instead of one?
Two latch holes let the same plate serve more than one latch position, so it works on openings where the existing latch centerline does not sit where a single-hole strike would put it, and on hardware with both a latchbolt and a deadbolt in range of the 12 inch plate. That is what makes it practical for a mixed door fleet where the prep heights are not identical from opening to opening.
3) How thick is the steel on the Don-Jo FL-212N6, and is it heavy enough for a pry-prone exterior door?
13 gauge, .095 inch ferrous steel. That is a heavy plate for a strike, which is the point of a security strike: it spreads a spreading or pry load across 12 inches of frame instead of concentrating it at the latch pocket. It is built for commercial service, not residential trim duty.
4) Is a security strike like the Don-Jo FL-212N6 the same thing as a strike box or a double-door strike kit?
No. The FL-212N6 is a flat face plate that mounts to the frame and reinforces the latch area over a 12 inch span. It is not a strike box (the pocket behind the frame) and it is not a paired-door kit. If you are securing a pair of doors on an exit device, that is a different part, such as the Detex 92 Strike Kit for double doors with tamper resistant fasteners. If you are adapting to a pipe-style application, the Trimco 1260P is a pipe adapter strike, strike only.
5) Do I have to buy the Don-Jo FL-212N6 strike in a multi-pack?
It is sold in shelf packs of 10. For a property manager or contractor hardening a run of doors that is the useful quantity, but if you need a single strike for one opening, know that you are buying ten.
6) I manage a building with mismatched strikes on every door. Can the FL-212N6 standardize them?
That is the case it fits. One 12 inch by 1-3/8 inch plate, two latch holes, and ten to a shelf pack means a run of doors with different latch heights and different-looking old strikes can end up looking and behaving the same. Pick one finish, brass plated or silver coated, and carry it across the fleet.
7) Will the Don-Jo FL-212N6 work on a residential wood door jamb?
It is built for commercial openings, and the 1-3/8 inch width is sized to commercial frame prep. On a residential wood jamb the flat of the stop face is often narrower than that, and a 13 gauge steel plate needs solid backing behind it to be worth anything. Check the flat width on your jamb before ordering; if it is under 1-3/8 inches, this is the wrong plate.
8) What finishes does the Don-Jo FL-212N6 come in?
Two: BP brass plated and SL silver coated. On a painted hollow metal frame the silver coated plate is the one that disappears under a coat of frame paint; brass plated is the match where the existing strike and hinges are brass tone. Since the plate is ferrous steel, either finish takes paint if you need it to match a custom frame color.
