Don-Jo ST-161-626 – Frequently Asked Questions

1) Will the Don-Jo ST-161 strike fit a standard ASA strike cutout in my frame?
Yes. The ST-161 is built to ASA strike dimensions, 4-7/8 inches by 1-1/4 inches, so it drops into a frame already prepped for a standard ASA (T-strike) cutout. That is the prep used on most commercial hollow metal frames carrying a cylindrical or mortise latch. If your frame is prepped for the smaller 2-3/4 x 1-1/8 residential strike, this one will not cover the opening without enlarging the mortise.
2) Can I use the ST-161 to replace a worn strike on a commercial door without changing the frame?
That is the usual job for it. The ST-161 matches the ASA prep already in the frame, so on an opening cut for a standard ASA strike it is a plate swap, two screws, no drilling. Pull the old plate first and measure it: if it is 4-7/8 by 1-1/4 you are a direct replacement. Handing is not a factor, since the plate is symmetrical top to bottom and gets flipped to suit the swing.
3) Does the ST-161 strike have a hole for a deadbolt as well as the latch?
No. It is a single latch hole strike, cut for the latchbolt only. If your lock is an interconnected or mortise unit throwing both a latch and a deadbolt into the frame, you need a two-hole ASA strike instead, or a separate deadbolt strike above it. The ST-161 works for cylindrical latches and for mortise locks where only the latch enters the frame at that point.
4) What strike should I use on a pair of doors with an exit device instead of an ASA strike?
Look at the Detex 92 Strike Kit from the 90 Strike Series, which is built for the double door condition and supplied with tamper resistant fasteners. The Don-Jo ST-161 is a single ASA lip strike for one latch bolt in a standard ASA frame prep - it is the right part for a typical single-door cylindrical or mortise latch, not for the mating strike arrangement on a pair. On a double door application, the Detex 92 kit is the one to spec.
5) Can a Trimco 1260P be used in place of a Don-Jo ST-161 ASA strike?
No - they solve different framing problems. The Don-Jo ST-161 is an ASA strike, the 4-7/8 inch x 1-1/4 inch flat lip plate that drops into a standard ASA cutout in a hollow metal or wood frame and takes a single latch bolt. The Trimco 1260P is a pipe adapter strike, made to pick up a latch on round pipe framing rather than a flat ASA prep. If the opening has a conventional flat frame with an ASA mortise, the ST-161 is the part; the 1260P is for the pipe-frame condition and will not fill or match an ASA cutout.
6) How thick is the Don-Jo ST-161 door strike plate?
The ST-161 is 13 gauge, .095 inch thick. That is heavier than the stamped strikes that ship in a residential lockset box, which matters on an opening that gets kicked, slammed, or run hard by traffic. On a frame prepped for a thinner strike you may need to deepen the mortise slightly so the plate sits flush.
7) Is the Don-Jo ST-161 strike magnetic or will it rust in a wet or coastal opening?
Non-ferrous, so it will not rust the way a plated steel strike does and it will not hold a magnet. That is the reason to pick it for exterior openings, pool and locker rooms, coastal buildings, and washdown areas in healthcare or food service. One thing to note if you use magnetic door position switches: a non-ferrous strike is not a magnetic target.
8) Do I need a strike box or dust box behind the ST-161?
The ST-161 is the face plate only, with no box attached. On a hollow metal frame the existing strike box or the frame cavity behind the prep takes the latch, so you generally reuse what is there. On a wood or aluminum frame with no box, add a separate ASA strike box so the latch has something to enter and the plate has backing.
9) For a coastal or wash-down facility, is the ST-161 the right strike or should I look at another option?
The Don-Jo ST-161 is built from non-ferrous material at 13 gauge (.095) for corrosion resistance, and comes in finishes including 626 satin chrome and 630 satin stainless steel, which is the usual choice where moisture is a factor. Neither the Detex 92 Strike Kit nor the Trimco 1260P is an ASA lip strike, so neither is a like-for-like alternate in a standard ASA prep - the substitution question there is about frame type, not environment. For an ASA cutout in a damp or corrosive environment, the ST-161 in 630 is the direct answer.
10) What finishes does the Don-Jo ST-161 ASA strike come in?
Seven, and they are the standard BHMA numbers so they match across brands on the same opening: 605 polished brass, 606 satin brass, 612 satin bronze, 613 oil rubbed bronze, 625 polished chrome, 626 satin chrome, and 630 satin stainless. If your building is standardized on 626 satin chrome or 630 satin stainless, those are the two that cover most commercial lever and mortise hardware.
11) How many Don-Jo ST-161 strikes come in a pack?
Shelf packs of 30. That suits a re-key or hardware refresh across a floor of doors rather than a single service call, and it is why property managers and MRO buyers standardize on one finish before ordering. Pick the finish that matches the rest of the building, since all 30 in a pack are the same one.
12) Is the Don-Jo ST-161 heavy duty enough for a school or hospital corridor door?
It is a commercial strike, not a residential one: 13 gauge .095 non-ferrous stock, sized to the ASA prep those buildings are already cut for. Schools, healthcare, offices, retail, warehouses, and multi-tenant residential are the openings it is meant for. The corrosion resistance of the non-ferrous material is the reason it holds up in humid or cleaned-down areas where a plated steel strike blisters.
