Don-Jo FL-212W4-SL – Frequently Asked Questions

1) Will the Don-Jo FL-212W4 strike cover the old cutouts and screw holes left in my frame?
The FL-212W4 is a 12 inch by 1-3/4 inch filler-style security strike, so it spans well beyond a standard strike prep and covers the damage and abandoned holes around it. That length is the reason to pick it over a small box strike: after a kick-in or a hardware change, you get one flat 13-gauge ferrous plate reinforcing the whole area instead of patching the frame. Two latch holes are punched in it, so it works where the frame carries two latch points.
2) I need a strike for a pair of doors with no mullion, is the FL-212W4 the right part?
No. The FL-212W4 is a flat frame-mounted security strike for a single latching point run of frame. For a double door application, look at the Detex 92 Strike Kit from the 90 Strike Series, which is built for double doors and comes with tamper resistant fasteners.
3) Is the Trimco 1260P a substitute for the Don-Jo FL-212W4 security strike?
No. The Don-Jo FL-212W4 is a 12 inch by 1-3/4 inch security strike in 13-gauge (.095) ferrous material with two latch holes, meant to reinforce a run of the frame around the latch. The Trimco 1260P is a pipe adapter strike, a strike-only part in the 1260 series built to let a latch engage a pipe or tubular frame member rather than a flat hollow metal jamb. If the opening is a standard commercial frame and the goal is frame reinforcement and forced entry resistance across a 12 inch length, the FL-212W4 is the part; the 1260P addresses a different frame condition entirely.
4) For a pair of double doors, should I order the Don-Jo FL-212W4 or the Detex 92 strike kit?
They solve different halves of the problem. The Detex 92 strike kit is a double door strike kit supplied with tamper resistant fasteners, part of the 90 strike series, so it is specified against a double door condition and comes as a kit. The Don-Jo FL-212W4 is a single 12 inch by 1-3/4 inch security strike in 13-gauge (.095) ferrous material with two latch holes, ordered per piece and applied wherever a jamb needs reinforcing behind the latch. On a double door opening driven by the Detex hardware, the 92 kit is the matched part; where the requirement is added frame strength at the latch on commercial doors generally, the FL-212W4 is the one to specify, and it is offered in BP brass plated, SL silver coated, and WH white coated.
5) Why does the FL-212W4 have two latch holes instead of one?
Two holes let one plate serve an opening with two latch points, a lock latch plus a deadbolt for example, without stacking two separate strikes on the frame. It also gives you some placement latitude on a retrofit, since one of the two holes can be lined up with the existing latch. If your opening has a single latch and nothing else, the second hole sits blank behind the plate.
6) Is 13-gauge ferrous steel heavy enough for a high-traffic commercial entrance?
13-gauge works out to .095 inch thick ferrous steel, which is the weight used for forced-entry reinforcement rather than trim. Don-Jo rates the FL-212W4 for commercial use, and it is the part you put on apartment entries, school corridors, and back-of-house doors that get abused. On a residential interior door it is far more plate than the opening needs.
7) How does a Don-Jo security strike differ from a pipe adapter strike like the Trimco 1260P?
Different jobs. The FL-212W4 is a 12 inch flat plate that reinforces and covers a run of door frame in 13-gauge ferrous steel. The Trimco 1260P from the 1260 Series is a pipe adapter strike, made to give a latch something to catch on a round pipe rail rather than a flat frame. If your latch is striking against tube or pipe, the flat Don-Jo plate has nothing to sit on.
8) I need tamper resistant screws with my strike. Does the Don-Jo FL-212W4 come with them?
Tamper resistant fastening is a defining feature of the Detex 92 strike kit, which is supplied for double doors with tamper resistant fasteners as part of the 90 strike series. The Don-Jo FL-212W4 is described by its plate: 12 inches high by 1-3/4 inches wide, 13-gauge (.095) ferrous, two latch holes, sold in shelf packs of 10 for stocking, in BP, SL, and WH finishes. If security screws are a stated requirement on the drawing, confirm fastener type before ordering, or specify the Detex kit where the opening is a Detex-equipped double door.
9) What finishes does the Don-Jo FL-212W4 security strike come in?
Three: BP brass plated, SL silver coated, and WH white coated. SL is the one that disappears against a typical aluminum or painted-gray commercial frame, WH matches white painted frames in multi-family and healthcare corridors, and BP goes with brass lever and lockset hardware. Since the plate is a repair part on a frame, match the frame color rather than the lockset.
10) Can I buy one Don-Jo FL-212W4, or does it come in a multi-pack?
It ships in shelf packs of 10. That suits the way the part actually gets used, standardizing a building's openings or keeping repair stock on the truck, but it does mean you are buying ten plates even for a single damaged frame.
11) Will a Don-Jo FL-212W4 strike plate rust if it is on an exterior door?
The substrate is ferrous, so the bare metal will corrode if it is left exposed to weather. All three versions carry a coating or plating (brass plated, silver coated, or white coated) that handles normal interior and covered-entry service. For a fully exposed exterior opening in a wet or coastal environment, plan on the finish being the only protection and inspect it for chips at install.
