Don-Jo ST-144-630 – Frequently Asked Questions

1) Is the Don-Jo ST-144 strike a single latch hole or does it have a separate deadbolt opening?
One hole only. The ST-144 is cut for a single latch, so it suits a latchbolt-only lock or a lockset where the deadbolt strikes separately. If you are replacing a T-strike or a double-hole plate that takes both a latch and a deadbolt in one plate, this is not the part.
2) Is the Detex 92 strike kit an equivalent replacement for the Don-Jo ST-144?
No, they solve different problems. The Don-Jo ST-144 is a replacement door strike with a single latch hole, 4-1/4 inch by 1-1/8 inch, in 13 gauge (.095) non-ferrous material, meant to drop into an existing frame prep on a standard single-latch assembly. The Detex 92 Strike Kit is a double door strike kit from the 90 Strike Series supplied with tamper resistant fasteners, so it addresses a pair of doors and comes as a kit rather than a single flat replacement plate. If the opening is one door and the frame is already prepped for a 4-1/4 inch strike, the ST-144 is the part that matches; a double door application is a different assembly, not a finish or size variation.
3) Will the Don-Jo ST-144 strike rust on an exterior or wash-down door?
The ST-144 is non-ferrous, in a 630 satin stainless finish, so it holds up on exterior openings, pool and locker corridors, kitchens, and coastal buildings where a plated steel strike bleeds rust down the frame. That is the main reason to spec it over a standard steel strike.
4) What finish does the Don-Jo ST-144 come in, and will it match my existing lever and hinges?
630 satin stainless is the only finish offered on the ST-144. It is the standard commercial finish, so it matches satin stainless levers, exit devices, and most brushed hardware on the same opening. Against US26D brushed chrome it reads very close but is not an exact match, and it will not blend with bronze or brass openings.
5) Do I need to worry about handing when ordering the Don-Jo ST-144 strike?
No. A flat single-hole strike plate like the ST-144 is symmetrical about the latch opening, so it goes on a left or right hand door the same way. Handing only enters into it for the lockset and any strike with a lip whose length is cut for one swing.
6) What is the difference between a Don-Jo ST-144 and a Trimco 1260P pipe adapter strike?
The Don-Jo ST-144 is a flat replacement door strike, 4-1/4 inch by 1-1/8 inch with one latch hole, formed in 13 gauge (.095) non-ferrous material and finished 630 satin stainless. The Trimco 1260P from the 1260 Series is a pipe adapter strike sold as the strike only, which is a strike built for a pipe application rather than a conventional flat frame face. A buyer replacing a damaged or mismatched strike in an ordinary commercial frame is looking at the ST-144 dimensions and hole count; the 1260P is specified when the mounting condition itself is the pipe adapter, so the two are not interchangeable even though both are called strikes.
7) For a pair of doors in a commercial building, should I order the Don-Jo ST-144 or something else?
A double door opening calls for a double door strike. The Detex 92 Strike Kit in the 90 Strike Series is built for double doors and ships with tamper resistant fasteners, which is what a pair of doors needs at the meeting point. The Don-Jo ST-144 is a single-latch-hole replacement strike measuring 4-1/4 inch by 1-1/8 inch in 13 gauge non-ferrous, so it suits the single-door leaves and standard commercial frames found in offices, schools, healthcare, retail, and multi-tenant residential. Facilities standardizing across a building often carry the ST-144 for the ordinary single-latch openings and specify the double door kit only where the opening is actually a pair.
8) I manage a building and need to standardize strikes across a lot of doors. Can I buy the ST-144 in bulk?
Yes, the ST-144 ships in a shelf pack of 30. That is the practical way to do a corridor or a whole floor at once, and it keeps one strike and one finish across the openings so a maintenance tech is not matching plates door by door.
9) Is the ST-144 meant for commercial doors or will it work on a house?
Don-Jo builds the ST-144 for commercial openings, and the 13 gauge non-ferrous plate is aimed at high-traffic frames in offices, schools, healthcare, retail, warehouses, apartment buildings, and municipal facilities. Nothing stops it going on a residential door, but you are paying for frame-strength material a house door does not usually need.
