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

1) What is the Don-Jo FL-212W security strike used for on a commercial door frame?
The FL-212W is a security strike that reinforces the frame around the latch. It's a 12 inch by 1-3/4 inch plate in 13-gauge (.095) ferrous material with a single latch hole, so it covers a long run of the jamb above and below the latch point rather than just the strike cutout. That extra coverage is what resists prying and kick-in at the latch. Commercial rated.
2) Will the Don-Jo FL-212W work on a pair of doors or a double door opening?
No. The FL-212W has one latch hole, so it serves a single latch point on one leaf. For a double door application you want a strike built for that, such as the Detex 92 Strike Kit for double doors, which comes with tamper resistant fasteners.
3) Will a 12 inch security strike fit my frame, or do I need to check something first?
Check the jamb face width and what's above and below the existing strike. The FL-212W needs a clear 12 inch run of flat jamb at 1-3/4 inches wide. On openings with a closer bracket, a hinge, or an electric strike box in that span, the plate won't lay flat. Measure from the existing strike cutout up and down before ordering the pack.
4) How much of the jamb does the 12 inch Don-Jo security strike cover compared to a standard strike plate?
A standard commercial ANSI strike is around 4-7/8 inches tall. The FL-212W runs 12 inches, so it spans roughly two and a half times that length of jamb, distributing force well beyond the latch pocket. Width is 1-3/4 inches, which suits a standard hollow metal jamb face.
5) Is the Don-Jo FL-212W sold individually or in a box?
It ships in shelf packs of 10. That works in your favor if you're standardizing a building or a corridor of units, since you get ten identical strikes in one finish rather than mixing plate lengths across openings.
6) What's the difference between a Don-Jo security strike and a pipe adapter strike?
Two different problems. The FL-212W is a flat reinforcing plate for a conventional jamb, 12 inches of 13-gauge ferrous steel with one latch hole. A pipe adapter strike like the Trimco 1260P is for mounting a strike to round tube or pipe framing, where a flat plate won't seat. If your frame is a standard hollow metal or wood jamb, the FL-212W is the one you want.
7) Can I paint or weld the Don-Jo FL-212W strike, and will a magnet stick to it?
The FL-212W is ferrous, so yes, a magnet holds and it takes standard metal primer and paint. Ferrous also means it will corrode if left bare in a wet or exterior opening, so the coated SL or WH versions are the better pick where moisture is a factor.
