Don-Jo MST-161-630 – Frequently Asked Questions

1) What latch does the MST-161 ASA strike work with?
Single latch hole, so it takes one latchbolt. That covers a cylindrical or mortise latch running into a standard ASA prep. It will not serve an opening where you need a second opening in the plate for a deadbolt, and it isn't a deadlatch-plus-deadbolt combination strike.
2) Can I use an ASA strike like the MST-161 on a pair of doors with no mullion?
No. An ASA strike mounts in the frame jamb and needs a frame to land in. On a pair of doors where the inactive leaf carries the strike, you need a strike made for that condition, such as the Detex 92 Strike Kit for double doors, which comes with tamper resistant fasteners. Use the MST-161 on single doors and on the active leaf of a pair fitted with a mullion.
3) Is the MST-161 a straight replacement for a worn or bent strike in an existing frame?
Yes, provided the frame is prepped for a 4-7/8 x 1-1/4 ASA strike. Pull the old plate, check the face dimensions against those, and if they match the MST-161 uses the same cutout and screw pattern. Don-Jo builds this one for both replacement work and new installs.
4) Is a 13 gauge strike heavy enough for a high-traffic commercial door?
13 gauge works out to .095 inch of material, which is the heavy end for a strike plate and is what holds up on doors cycling all day in offices, schools, and healthcare corridors. Thinner strikes distort around the latch hole over time and start dragging the latch. The MST-161 is built as a commercial product, not a residential one.
5) Will the MST-161 strike rust on an exterior or wash-down door?
The plate is non-ferrous, so there's no steel substrate to rust out, and the 630 satin stainless finish keeps its appearance in humid and frequently cleaned areas. That makes it a reasonable choice for entry vestibules, locker rooms, and kitchens where a plated steel strike would eventually bloom rust around the screw heads.
6) What's the difference between an ASA strike and a pipe adapter strike?
Different mounting problem entirely. The MST-161 is a flat ASA strike for a prepped frame jamb. A pipe adapter strike, like the Trimco 1260P from the 1260 Series, is shaped to land on round tube or pipe framing where there's no flat jamb face to screw into, which is common on aluminum and rail assemblies. If you're screwing into a hollow metal frame, you want the ASA strike.
7) Does the Don-Jo MST-161 come in any finish other than 630?
630 satin stainless is the only finish the MST-161 is built in. That's the standard commercial hardware finish and it matches 630 levers, exit devices, and closers already hung in most institutional buildings, so a facility standardizing on 630 can keep the strikes consistent with everything else on the opening.
8) I need to restrike a lot of doors in one building. How does the MST-161 come packed?
It's sold in a shelf pack of 30 strikes, which suits a contractor doing a floor at a time or a maintenance shop keeping a bin of spares. For a property manager standardizing a building on one strike, buying the pack keeps every opening on the same plate and the same 630 finish.
