Don-Jo SMEST-103-630 – Frequently Asked Questions

1) Will the Don-Jo SMEST-103 fit a standard ASA strike prep in my frame?
Yes. The SMEST-103 is an ASA (T-strike) format plate measuring 4-7/8 inches by 3 inches, which is the standard ASA cutout size commercial hollow metal frames are prepped for. The 3 inch width is measured from the center of the screw hole to the end of the lip, so the extra width is all lip projection past the frame face, not extra plate sitting in the mortise. If your existing strike is a 4-7/8 x 1-1/4 ASA, this drops into the same prep and gives you a longer lip.
2) When do I need an extended lip strike instead of a standard ASA strike?
Use an extended lip when the frame is set back from the door face, when there is a deep stop or an applied trim the latch has to ride over, or when a mismatched frame leaves the standard lip short and the latch drags on the jamb. The SMEST-103 gives you 3 inches from screw hole center to the end of the lip, so the lip runs well past the frame face and guides the latch in. If your door and frame are flush and the latch already closes clean, a standard 1-1/4 inch lip ASA strike is all you need and the extended lip just projects into the opening.
3) What should I use for the strike on a pair of double doors instead of an ASA lip strike?
An extended lip ASA strike like the Don-Jo SMEST-103 is made to mount in a frame jamb and throw a lip toward the door, which is the wrong geometry at the meeting point of a pair of doors where there is no jamb to catch. For that opening, the Detex 92 Strike Kit is a double door strike kit from the 90 Strike Series and comes with tamper resistant fasteners, so the strike hardware cannot be backed out from the accessible side. Keep the SMEST-103 for the hinge-jamb side single door openings and the Detex 92 kit for the double door application.
4) Is a Trimco 1260P the same kind of strike as a Don-Jo SMEST-103?
No. The Trimco 1260P is a pipe adapter strike from the 1260 Series and is supplied as the strike only, meaning it is built to interface with a pipe condition rather than a standard prepped frame. The Don-Jo SMEST-103 is an extended lip ASA strike in non-ferrous construction, cut for a conventional ASA frame prep with the lip extended to carry the latch across a returned or offset jamb. They are not interchangeable orders even though both are called strikes, so confirm which frame condition you are working with before substituting one for the other.
5) Does the Don-Jo SMEST-103 strike work with a lock that has a deadbolt as well as a latch?
It has two latch holes, so it accepts a latchbolt and a second bolt in the same plate, which is the arrangement on ASA prep for a mortise lock with a deadbolt or an auxiliary deadlatch. For a single cylindrical latch you only use the one opening.
6) Is the Don-Jo SMEST-103 strike heavy enough for a high traffic commercial door?
It is built to 13-gauge (.095 inch) thickness, which is a heavy strike plate rather than a light residential stamping, and it is rated commercial rather than residential. That gauge is what keeps the lip from deforming when a latch slams into it repeatedly on a school corridor or an office entry.
7) Will a Don-Jo SMEST-103 strike rust in an exterior or wash-down opening?
The plate is non-ferrous, so it does not carry the corrosion problem a plain steel strike has at an exterior door, a pool corridor, or a healthcare wash-down area. The 630 satin stainless finish is the usual pick for those openings.
8) What is the difference between a Don-Jo SMEST-103 and a Detex 92 strike kit?
Different jobs entirely. The SMEST-103 is a flat extended lip ASA strike that mounts in the frame jamb prep for a latch or mortise lock. The Detex 92 Strike Kit, from the Detex 90 Strike Series, is for a double door application and comes with tamper resistant fasteners, so it goes with an exit device on a pair rather than into an ASA frame prep. If you are replacing a strike behind a cylindrical or mortise lockset, the SMEST-103 is the ASA plate; the Detex is not a substitute for it.
9) I need a strike that resists someone unfastening it from the outside. What are my options?
The Detex 92 Strike Kit ships with tamper resistant fasteners as part of the kit, which is the direct answer when the concern is the strike being removed at the opening. The Don-Jo SMEST-103 is a commercial extended lip ASA strike in non-ferrous material and is specified on the strength of the strike itself, 13-gauge at .095 thickness with two latch holes, rather than on the fastener type. If the fastener is the deciding factor, the Detex 92 kit is the one to quote; if the requirement is a heavy commercial ASA lip strike in a standard frame prep, the SMEST-103 covers it.
10) What finishes does the Don-Jo SMEST-103 extended lip strike come in?
Three: 622 matte black, 630 satin stainless steel, and DU duronodic brown coated. 630 is the common commercial match for stainless and satin chrome lever trim, 622 pairs with matte black hardware, and DU is the one to order when you are matching dark bronze aluminum storefront and older duronodic entrances.
11) How is the Don-Jo SMEST-103 sold, and can I buy just one?
It ships in shelf packs of five. For a property manager standardizing strikes across a building or a contractor doing a floor of doors that quantity works out, but it does mean a single-door repair leaves you with spares on the shelf.
