Don-Jo SMEST-115-622 – Frequently Asked Questions

1) What is an extended lip strike for, and do I need one instead of a standard ASA strike?
An extended lip is what you order when the door is set back from the jamb face, or when a wrap-around frame, applied stop, or thick trim leaves the latch running over an edge on its way in. The longer lip carries the latch across that gap and guides it into the pocket instead of letting it catch. On the SMEST 115 that lip runs out to 1-1/2 inches from the center of the screw hole. If your latch already lands square on a flush jamb, a standard ASA lip is all you need and the extra lip just projects into the opening.
2) Can I use the Don-Jo SMEST 115 on a pair of doors with no mullion?
No. The SMEST 115 is a lipped ASA strike that mounts in the frame jamb, so it needs a jamb or mullion to land on. For a double door with no mullion, the strike goes on the inactive leaf and that is a different part - the Detex 92 Strike Kit from the 90 Strike Series is a double door strike kit and includes tamper resistant fasteners.
3) What should I use instead of a Don-Jo SMEST 115 when the latch has to catch on a round post rather than a flat frame?
Look at the Trimco 1260P instead. The 1260P is a pipe adapter strike from the Trimco 1260 Series, sold as the strike only, and it is built to adapt a latch to a pipe or round post condition. The Don-Jo SMEST 115 is an extended lip ASA strike, a flat plate cut for a conventional ASA strike prep in a door frame, so it assumes a flat jamb face to screw to. Gates, railings and tube frame openings are the 1260P's territory; standard commercial hollow metal and wood frames are the SMEST 115's.
4) Is the Detex 92 strike kit an equivalent replacement for a Don-Jo SMEST 115 extended lip ASA strike?
No, they solve different problems. The Don-Jo SMEST 115 is an extended lip ASA strike for a commercial door, a single strike plate whose lip is extended to guide the latch into positive engagement. 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 and at openings where the fastener heads need to resist attack. If you are replacing a standard ASA strike in a single frame and the latch is fighting a deep or out of plumb jamb, the extended lip SMEST 115 is the part. If the opening is a double door assembly being fitted with matching Detex hardware, the 92 kit is the one to look at.
5) Why does the Don-Jo SMEST 115 have two latch holes?
Two latch holes let the one strike serve locksets with a latchbolt plus an auxiliary deadlatch or secondary bolt, rather than a single latch opening. That covers the common commercial cylindrical and mortise latch layouts without a special order.
6) Is a non-ferrous strike worth it for exterior or wash-down doors?
Non-ferrous is the reason to pick the SMEST 115 over a plain steel strike on openings that see moisture, salt air, or frequent cleaning chemicals: there is no ferrous base metal to rust out from under the finish where the latch scrubs the lip. It is built at 13-gauge (.095) so it still takes the hammering of a high traffic entrance.
7) Is the Don-Jo SMEST 115 rated for residential doors or commercial only?
Commercial. It is a 13-gauge (.095) non-ferrous ASA strike sized to the 4-7/8 inch commercial frame prep, which is not what a typical residential door jamb is bored for. Residential prehung doors normally take a small face strike and would need the jamb cut to accept this one.
8) Does the Don-Jo SMEST 115 strike have a handing?
The lip has a direction, so you order to match which way the latch travels into the strike. Check which side the lip extends toward on the door you are replacing before you order, because the 1-1/2 inch lip is what makes the strike work and a reversed one puts it on the wrong side of the opening.
9) I need a strike plus the screws to secure it against tampering. Does the Don-Jo SMEST 115 cover that, or do I need a kit?
The Don-Jo SMEST 115 is an extended lip ASA strike itself, built from non-ferrous material for corrosion resistance in commercial service, and the Trimco 1260P is likewise supplied as the strike only. If tamper resistant fasteners are part of what you are buying, the Detex 92 Strike Kit is the item that includes them, and it is configured for a double door opening in the Detex 90 Strike Series. Locksmiths retrofitting a single frame usually stay with the SMEST 115 and source fasteners to match the frame condition.
10) What finishes does the Don-Jo SMEST 115 ASA strike come in?
Three: 622 matte black, 630 satin stainless steel, and DU duronodic brown coated. For a building already standardized on 630 lever trim, the 630 strike is the match; DU is the one that blends with dark bronze anodized aluminum entrances, and 622 with black hardware sets.
11) How many strikes come in a pack of the Don-Jo SMEST 115?
They ship in shelf packs of 5. That suits a property manager doing a floor of doors or a locksmith keeping a couple of finishes on the truck; for a single door replacement you will still have four spares.
