Don-Jo A-2-SS-BP – Frequently Asked Questions

1) Will the Don-Jo A-2 adjustable strike work with a key-in-knob lockset?
That's exactly what it's built for. The A-2-SS is an adjustable strike with a single latch hole sized for key-in-knob locks, so one cylindrical latch drops into one opening. If you're replacing a strike for a lever or knob cylindrical lockset, this is the right family. It is not a mortise strike and it has no deadbolt hole, so a lock with a separate deadbolt above the latch needs a two-hole or T-strike instead.
2) What does "adjustable" mean on a Don-Jo A-2 strike, and will it fix a door that isn't latching?
Adjustable means the latch engagement can be tuned in place rather than being fixed by the stamping, so minor door and frame variation gets taken up without re-mortising the jamb. On a door that rattles or misses the keeper because the frame has shifted or the hinges have sagged slightly, an adjustable strike like the A-2-SS is the usual fix. It will not correct a gross misalignment where the latch lands off the 1-1/4 by 3-3/4 inch strike footprint entirely, that's a frame or hinge problem.
3) Will a 1-1/4" x 3-3/4" strike cover the cutout my old strike left in the frame?
The A-2-SS measures 1-1/4 inches wide by 3-3/4 inches tall, which is the standard ANSI cylindrical strike footprint used on most commercial hollow metal frames. Pull your existing strike and measure the plate, if it is the same 1-1/4 by 3-3/4 it swaps straight in on the existing screw holes and lip mortise. If the old plate is 1-1/8 wide, or 4-7/8 tall (the ANSI full-lip size), this one will not cover the mortise and you want the matching size instead.
4) I need a strike for a pair of doors with no mullion, will the Don-Jo A-2 work?
No. The A-2-SS mounts in a frame jamb for a single cylindrical latch. A pair of doors without a center mullion has no jamb at the meeting stile to mount it to. For that opening look at the Detex 92 Strike Kit, a double door strike kit from the 90 Strike Series that includes tamper resistant fasteners. If you're latching into pipe or a round post rather than a flat jamb, the Trimco 1260P pipe adapter strike is the part for that condition.
5) Is the Detex 92 strike kit an alternative to the Don-Jo A-2-SS adjustable strike?
They solve different openings. The A-2-SS is an adjustable strike for key-in-knob locksets, with a knob-type handle application and a single latch hole in 13-gauge ferrous material at 1-1/4 inch by 3-3/4 inch. The Detex 92 Strike Kit is a double door strike kit from the Detex 90 Strike Series, supplied with tamper resistant fasteners. If the frame takes a standard key-in-knob latch, the A-2-SS is the strike; if the job is a double door running Detex 90 Series hardware, the 92 kit is what that opening is built around.
6) What is the difference between the Trimco 1260P and the Don-Jo A-2-SS strike?
The Trimco 1260P is a pipe adapter strike from the Trimco 1260 Series, supplied as a strike only, and it is built to land on a pipe or tube condition rather than a conventional flat frame. The Don-Jo A-2-SS is a 1-1/4 inch by 3-3/4 inch adjustable strike for key-in-knob locksets, 13-gauge (.095) ferrous, with one latch hole, and its adjustability is there to take up minor door and frame variation on a standard commercial opening. Match the part to the frame you actually have: pipe or tube frame points to the 1260P, a standard prepped commercial frame with a key-in-knob lockset points to the A-2-SS.
7) Is 13 gauge steel heavy enough for a strike on a high-traffic commercial door?
13 gauge works out to .095 inch thick ferrous steel, which is the weight specified for commercial openings rather than residential, and it's what keeps the keeper from deforming when a latch is driven into it thousands of times a year. On a stairwell, classroom, or tenant corridor door the A-2 is rated commercial for that reason. Residential strikes are typically thinner stamped brass or 20-something gauge and will curl under that traffic.
8) Does a Don-Jo A-2 strike have a handing, or does one part work on both left and right hand doors?
No handing to specify. A cylindrical strike plate is symmetrical top to bottom, and the lip that guides the latch works the same whether the door swings left or right, so one A-2-SS covers either. What you do need to match is the frame material and the existing mortise, and whether your lock is a knob or lever cylindrical (this one) versus a mortise lock.
9) Can I standardize one strike across all the doors in my building with the Don-Jo A-2?
Across the cylindrical knob and lever openings, yes, that's the case for it: one non-handed part number, two finishes, packed 10 to a shelf pack, and the adjustability absorbs the small frame-to-frame variation you get in an older building. Where it stops is any opening that isn't a single door with a single cylindrical latch in a flat jamb. Mullion-less pairs and pipe-frame openings need different parts, and mortise locks need a mortise strike.
10) I need a strike for a commercial key-in-knob lockset - which one do I order?
The Don-Jo A-2-SS is the one purpose-built for that: an adjustable strike listed for knob-type hardware, 1-1/4 inch wide by 3-3/4 inch tall, 13-gauge (.095) ferrous, single latch hole, in BP brass plated or SL silver coated, sold in shelf packs of 10 for multi-door work. The Trimco 1260P is a pipe adapter strike and the Detex 92 is a double door kit in the Detex 90 Strike Series - both are shaped by the frame or exit hardware they serve rather than by a key-in-knob latch, so neither drops into a standard knob opening in place of the A-2-SS.
11) What finishes does the Don-Jo A-2 adjustable strike come in?
Two: BP, brass plated, and SL, silver coated. The strike is ferrous steel underneath in both cases, so the finish is a coating over steel and not solid brass. For a building standardized on brass or bright brass knobs, take BP; for chrome, satin chrome, or aluminum-finish hardware, SL reads closer. The strike sits in the jamb behind the door edge, so an exact match to the lockset matters less here than it does on a rose or lever.
12) Do I have to buy a whole box of Don-Jo A-2 strikes, or can I get one?
The A-2-SS is packed in shelf packs of 10. That suits the way it actually gets bought, a property manager retrofitting a floor of tenant doors or a contractor trimming out a building goes through them, and having spares on the truck beats a second trip when one strike turns out to be wrong. For a single-door repair, ten is more than the job needs.
