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

1) What is the Don-Jo FL-212N security strike used for on a commercial door?
The FL-212N is a filler-style security strike plate that covers the strike area of a commercial frame. It's 12 inches by 1-3/8 inches with a single latch hole, so one latch passes through and the rest of the plate armors the surrounding frame face. It is a strike plate only, not a lock or a latch, so it goes on with whatever lockset the opening already has.
2) Will the Don-Jo FL-212N work if my door has two latch points, like a lock and a deadbolt?
No. The FL-212N is drilled with one latch hole only, so it suits a single latching point. An opening with a separate deadbolt above the lockset needs a strike with two holes, or a second strike, since there is no cutout for the second bolt in this plate.
3) Is the Detex 92 strike kit an equivalent to the Don-Jo FL-212N security strike?
They solve different openings. The Don-Jo FL-212N is a 12 inch by 1-3/8 inch security strike with a single latch hole, made from 13-gauge (.095) ferrous material for commercial door frames. The Detex 92 Strike Kit is a double door strike kit from the 90 Strike Series supplied with tamper resistant fasteners. If you are covering a single frame lip on a standard latch opening, the FL-212N is the part; if you are striking a pair of doors, the Detex 92 kit is the one built for that condition.
4) How thick is the metal on the Don-Jo FL-212N strike?
13 gauge, .095 inch ferrous steel. That's the reason to specify this plate over a light stamped strike: on a frame that's been kicked or pried, the heavy plate spreads the load across 12 inches of frame face instead of the few inches around the latch. Ferrous means it will take a magnet and will rust if the coating is broken, so keep it to interior or protected openings.
5) Do I order the FL-212N by handing, left or right?
Handing doesn't apply. The FL-212N is a symmetrical 12 by 1-3/8 inch plate with a single latch hole, so it takes either hand of door. The only choice on the order is finish, BP brass plated or SL silver coated.
6) What finishes does the Don-Jo FL-212N come in?
Two: BP brass plated and SL silver coated. Both are plated or coated over the ferrous steel body, so pick whichever reads closer to the existing lock trim on the opening. For a fleet of doors in a building, standardizing on one of the two keeps the frames matching as strikes get replaced over time.
7) How many Don-Jo FL-212N strikes come in a pack?
They ship in shelf packs of 10. That suits a contractor or facility crew doing a run of openings at once rather than a single-door repair, so plan the order around the number of frames being covered.
