Don-Jo SMEST-125-630 – Frequently Asked Questions

1) What size is the Don-Jo SMEST-125 ASA strike, and will it fit a standard 4-7/8 inch ASA frame prep?
The SMEST-125 is a 4-7/8 inch by 2-1/2 inch extended lip ASA strike, so it drops into the standard 4-7/8 inch ASA (T-strike) frame cutout used on commercial hollow metal frames. Note how the 2-1/2 inch is measured: from the center of the screw hole to the end of the lip, not overall face width. That is the number that decides whether the lip clears your trim or stop.
2) When do I need an extended lip strike instead of a standard ASA strike?
You need the extended lip when the frame sits back from the door face, on a deep stop, a wrapped or applied casing, or a frame set proud of the wall, so the latch would otherwise ride across bare frame before it reaches a standard lip. The extra lip on the SMEST-125 carries the latch across that gap and lets it ride onto the strike cleanly. If your frame face is flush with the door edge and the latch already lands on the strike, a standard-lip ASA strike is the simpler part.
3) Will the Don-Jo SMEST-125 strike work with a cylindrical lockset and a deadbolt in the same opening?
The SMEST-125 has two latch holes, which is what lets one strike take a latchbolt and a second bolt in the same frame cutout rather than requiring two separate strikes. It is cut for standard commercial latch bolt configurations. Match your existing frame prep before you order: if your frame is cut for a single-hole ASA strike, a two-hole face will not line up with the mortise pocket.
4) I have a round pipe or tube frame, not a hollow metal frame. Will the Don-Jo SMEST-125 strike mount to it?
No. The SMEST-125 has a flat 4-7/8 by 2-1/2 inch ASA face that needs a flat frame with an ASA mortise prep. For a round pipe or tube column, the part to look at is the Trimco 1260P pipe adapter strike from the 1260 Series, which is built to adapt a strike to pipe.
5) Is the Detex 92 strike kit an alternative to the Don-Jo SMEST-125 extended lip ASA strike?
They solve different openings. The SMEST-125 is an extended lip ASA strike in non-ferrous construction for a single latch opening in a commercial door frame. The Detex 92 Strike Kit is a double door strike kit from the Detex 90 Strike Series and ships with tamper resistant fasteners, so it is aimed at a pair of doors rather than at replacing an ASA strike in a frame. If the opening is a single door with a standard ASA strike prep, the SMEST-125 is the direct part; if you are strike-mounting a double door assembly, the Detex 92 kit is the one to look at.
6) A parts list calls out a Trimco 1260P strike. Will a Don-Jo SMEST-125 take its place?
No. The Trimco 1260P is a pipe adapter strike from the Trimco 1260 Series, sold as the strike only, and a pipe adapter strike is prepped to work with a pipe application rather than to fill an ASA strike cutout. The Don-Jo SMEST-125 is an extended lip ASA strike, 4-7/8 inches high by 2-1/2 inches wide with the width measured from the center of the screw hole to the end of the lip, with two latch holes. Order the SMEST-125 when the frame is prepped for a 4-7/8 inch ASA strike and you need lip projection to reach the latch; order the 1260P when the drawing specifically calls for the pipe adapter.
7) How thick is the Don-Jo SMEST-125 strike, and will it hold up in a high traffic entrance?
It is 13-gauge, .095 inch material, which is heavy for a strike face and is the reason it is specified for commercial rather than residential openings. That thickness is what resists deformation where the latch hits the lip thousands of times a week, in schools, offices, healthcare buildings and retail entries.
8) Is the Don-Jo SMEST-125 strike okay for an exterior door or a coastal, wet, or pool environment?
The SMEST-125 is non-ferrous, so it does not rust the way a plated steel strike does. That matters on exterior openings, natatoriums, coastal buildings, kitchens and wash-down areas, where a ferrous strike will bleed rust down the frame long before it fails mechanically. Paired with the 630 satin stainless finish, it is the version to specify where corrosion is the issue.
9) What finishes does the Don-Jo SMEST-125 ASA strike come in?
Three: 622 matte black, 630 satin stainless steel, and DU duronodic brown coated. 630 is the one that matches most commercial stainless lever and exit hardware. 622 goes with matte black trim packages, and DU matches dark bronze aluminum storefront and older duronodic entrances, which is the finish people most often struggle to source when replacing a single damaged strike.
10) Does the Don-Jo SMEST-125 strike have a hand, or does one part work on both left and right hand doors?
An ASA strike like the SMEST-125 is not handed. The face is symmetrical top to bottom and you flip it to suit the swing, so one part number covers left hand and right hand openings. What you do have to get right is the lip: it has to project toward the door face on your particular frame, and the extended lip only helps if the frame is set back from the door.
11) For a locksmith standardizing strikes across a commercial building, which of the Don-Jo SMEST-125, Detex 92 kit, and Trimco 1260P is the one to stock in quantity?
The Don-Jo SMEST-125 is the stocking item for general single-door commercial openings: it is a commercial extended lip ASA strike in 13-gauge (.095) non-ferrous material, sold in shelf packs of 5, and offered in 622 matte black, 630 satin stainless steel, and DU duronodic brown coated so it can be matched to the finishes already on the building. The Detex 92 Strike Kit is a double door kit in the Detex 90 Strike Series and the Trimco 1260P is a pipe adapter strike, both of which are opening-specific parts you buy for the doors that call for them rather than stock across a facility.
12) How many Don-Jo SMEST-125 strikes come in a pack?
They ship in shelf packs of 5. For a property manager or MRO stockroom that is usually the right unit, since strikes get replaced one opening at a time and a pack of five covers a floor's worth of damaged frames. Contractors standardizing a building on one finish should count openings and order in multiples of five.
