Don-Jo SMEST-104-630 – Frequently Asked Questions

1) Will the Don-Jo SMEST-104 fit a standard ASA strike prep in my frame?
The SMEST-104 is an ASA strike measuring 4-7/8 x 4 inches, which is the standard ASA (T-strike) frame cutout height, so it drops into a frame already prepped for a 4-7/8 inch strike. The 4 inch figure is the width measured from the center of the screw hole to the end of the lip, so the extra length sits out past the frame face as lip, not inside the cutout. If your existing frame is prepped for a 4-7/8 inch ASA strike, this replaces it without new cutting.
2) Is the Don-Jo SMEST-104 strike suitable for an exterior or coastal door where a steel strike rusts out?
Non-ferrous is the point of this one. The SMEST-104 is built from 13-gauge (.095) non-ferrous material, so there is no steel to rust at the lip where water sits. That makes it a reasonable pick for exterior openings, pool and locker rooms, and coastal buildings where plated steel strikes bleed rust down the frame. Order it in 630 satin stainless steel if you want the finish to hold up as well as the substrate.
3) I have a pair of doors with no mullion. Is this ASA strike the right part?
No. The SMEST-104 is a frame-mounted ASA strike for a single door latching into a jamb. A pair of doors with no center mullion needs a strike made for that condition, such as the Detex 92 Strike Kit for double doors, which is supplied with tamper resistant fasteners. Use the ASA strike only where the latch lands in a frame.
4) Is the Detex 92 strike kit an equivalent replacement for a Don-Jo SMEST-104 extended lip ASA strike?
No - they solve different openings. The SMEST-104 is an extended lip ASA strike, the flat plate mortised into the frame of a single swinging door so a latch bolt can catch it, and it is built in non-ferrous material for commercial use. The Detex 92 Strike Kit belongs to the 90 Strike Series and is a double door strike kit supplied with tamper resistant fasteners, so it addresses the meeting stile of a pair of doors rather than a standard ASA frame prep. If the door in front of you is a single leaf with an ASA cutout already in the frame, the SMEST-104 is the part that drops into it; a pair of doors with an exit device is the case for the Detex kit.
5) What strike should I use if the latch is catching a pipe rail instead of a door frame?
Use a pipe adapter strike such as the Trimco 1260P, which is from the 1260 Series and is sold as the strike only. It is shaped to adapt to a round pipe section rather than a flat frame face. The Don-Jo SMEST-104 will not serve there: it is an extended lip ASA strike with two latch holes, dimensioned 4-7/8 inch high by 4 inch wide measured from the center of the screw hole to the end of the lip, and that geometry assumes a standard flat ASA frame prep. Match the strike to what the latch is landing on - flat frame prep gets the SMEST-104, pipe gets the 1260P.
6) Why would I use an extended lip strike instead of a standard ASA strike?
An extended lip carries the latch further out from the frame face. That is what you want when the door is set back in the opening, when there is heavy trim or an applied stop, or when the latch is riding the frame edge and scarring it on close. The SMEST-104 gives you 4 inches from the center of the screw hole to the end of the lip. If your latch already engages cleanly with a flush strike, a standard-lip ASA strike is the simpler part.
7) What does the 2 latch hole configuration on the SMEST-104 mean for my lockset?
Two latch holes means the strike plate is punched for both a latchbolt and a separate auxiliary or deadlocking element, so it takes locksets that present two bolts at the frame rather than only a single latch. If your lock throws just one latchbolt, the second opening is simply unused. Check what your lock front presents at the jamb before ordering, because a single-hole ASA strike will not accept a two-bolt lock front.
8) Is the SMEST-104 heavy enough for a high-traffic commercial door?
13-gauge (.095) material is the commercial weight for a strike, and the SMEST-104 is rated for commercial rather than residential use. That is the gauge you want on office, school, healthcare, and retail entrances where the latch takes constant cycling and the lip gets kicked. A thinner residential strike will dish at the lip in that service.
9) My latch strikes against a pipe or round post, not a flat jamb. Will this strike work?
It will not. The SMEST-104 mounts flat to a frame face and needs a flat jamb behind it. For a latch engaging a round post, the Trimco 1260P pipe adapter strike from the 1260 Series is the part built for that geometry. Trying to force a flat ASA strike onto a curved surface leaves the plate unsupported and the latch under-engaged.
10) Do any of these commercial strikes come with the fasteners, or do I order screws separately?
It varies by part, so check before the truck rolls. The Detex 92 Strike Kit is supplied as a kit with tamper resistant fasteners included, which is what you want on an exposed double door meeting stile. The Trimco 1260P is sold as the strike only. The Don-Jo SMEST-104 extended lip ASA strike is packed as a shelf pack of 5 units, which suits a property manager or contractor standardizing several openings in one order across finishes 622, 630, and DU.
11) What finishes does the Don-Jo SMEST-104 come in, and which one matches my existing hardware?
Three finishes: 622 matte black, 630 satin stainless steel, and DU duronodic brown coated. 630 is the usual match for commercial levers and exit devices on aluminum or hollow metal openings, 622 pairs with matte black hardware, and DU is the dark bronze anodized look used on older storefront and aluminum entrances. Pick the strike finish off whatever is on the lock, not off the frame paint.
12) How many Don-Jo SMEST-104 strikes come in a pack?
The SMEST-104 is sold in a shelf pack of 5. That works out well if you are standardizing strikes across a floor or a building and want spares on the truck, but it is worth knowing before you order for a single door replacement.
