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

1) Will the Don-Jo MEST-103 fit a standard ASA strike prep in my existing frame?
Yes. The MEST-103 is cut to the ASA (ANSI) strike footprint at 4-7/8 inches by 3 inches, so it drops into a frame already prepped for a standard ASA strike with a single latch hole. The 3 inch dimension is measured from the center of the screw hole to the end of the lip, not overall face width, which is how the extended lip picks up doors that sit back from the frame face.
2) Does the MEST-103 strike work with a deadbolt as well as the latch?
No. The MEST-103 has one latch hole only, so it takes the latchbolt from a cylindrical or mortise lock and nothing else. If the opening has a separate deadbolt above the lockset, that deadbolt needs its own strike, and if you have a mortise lock throwing both a latch and a deadbolt through one prep you need a two-hole ASA strike instead.
3) Is the Don-Jo MEST-103 the right strike for a pair of doors with no mullion?
No. The MEST-103 is a frame-mounted ASA strike, so it needs a jamb to screw into. On a pair of doors where the inactive leaf carries the strike, or on a double door exit device setup, you want a purpose-built double door strike kit such as the Detex 92 Strike Kit, which is made for that condition and comes with tamper resistant fasteners.
4) I have a round pipe or tube frame, not a flat jamb. Can I use the MEST-103?
Not directly. A flat ASA strike like the MEST-103 needs a flat jamb face to sit against; on round pipe or tube framing it will rock and the screws will not draw down. For that condition look at the Trimco 1260P pipe adapter strike, which is built to bridge a pipe section.
5) Can a Detex 92 Strike Kit be used in place of a Don-Jo MEST-103 extended lip ASA strike?
No, they solve different problems. The MEST-103 is an extended lip ASA strike in non-ferrous material, sized 4-7/8 inches high by 3 inches wide with the width taken from the center of the screw hole to the end of the lip, and it gives a standard latchbolt a single latch hole to engage in an ASA frame prep. The Detex 92 Strike Kit is part of the Detex 90 Strike Series and is a double door strike kit supplied with tamper resistant fasteners, so it is the piece you order for a pair of doors with no fixed frame member to strike into. If the opening is a single door with an ASA prep in the frame, the MEST-103 is the strike; if you are strikng an active leaf against an inactive leaf on a double door, the 92 kit is the one to look at.
6) What is the difference between a Trimco 1260P pipe adapter strike and a Don-Jo MEST-103 ASA strike?
They mount to different things. The Trimco 1260P is a pipe adapter strike from the Trimco 1260 Series, sold as the strike only, and it is intended to adapt a strike to round pipe rather than to a flat frame face. The Don-Jo MEST-103 is an extended lip ASA strike, 4-7/8 inches by 3 inches with a single latch hole, made to drop into a standard ASA strike preparation in a commercial hollow metal or aluminum frame. A locksmith working a glass-and-pipe or railing-style opening reaches for the pipe adapter; a locksmith working a prepped commercial frame reaches for the ASA strike. Neither one will sit correctly in the other's application.
7) What does the extended lip on the MEST-103 strike actually do for me?
The extended lip carries the latch ramp further out past the frame face, so it works where the door is set back from the jamb or where there is a gap that leaves a standard-lip strike short. The latch rides the longer lip in and seats cleanly instead of catching the edge. On the MEST-103 that lip runs out to 3 inches measured from the center of the screw hole.
8) Is the Don-Jo MEST-103 strike heavy enough for a high-traffic commercial entry?
It is built at 13 gauge (.095) thickness and rated commercial, which is the material weight you want on an opening that gets hit all day, an office corridor, a school, a healthcare wing. Thinner residential strikes deform at the lip under that kind of cycling; 13 gauge does not.
9) Will a non-ferrous strike hold up in a coastal or wash-down environment?
Non-ferrous is the reason to pick this one. The MEST-103 is made from a non-ferrous substrate, so there is no steel in the strike to rust out at the lip where water sits. That matters on exterior openings, pool and locker areas, and any door that gets hosed down. Steel strikes in those spots bleed rust down the frame within a season.
10) What finishes does the Don-Jo MEST-103 come in, and which matches my existing hardware?
Three: 622 matte black, 630 satin stainless steel, and DU duronodic brown coated. 630 is the one to order if the rest of the opening is satin stainless lever and closer hardware, which is the common commercial default. DU matches dark bronze storefront and aluminum entrance packages. 622 goes with matte black trim.
11) I need a strike for a commercial door frame and I am comparing a few - which one is the standard replacement?
For a single commercial door with a standard ASA frame cutout, the Don-Jo MEST-103 is the direct-fit choice: it is a 4-7/8 inch by 3 inch extended lip ASA strike in 13 gauge (.095) non-ferrous material with one latch hole, in 622 matte black, 630 satin stainless steel, or DU duronodic brown coated to match the rest of the trim on the opening. The two other strikes commonly seen alongside it are application-specific rather than general replacements - the Detex 92 Strike Kit is a double door kit in the 90 Strike Series with tamper resistant fasteners, and the Trimco 1260P is a pipe adapter strike from the 1260 Series. A property manager restocking strikes across a building of standard commercial openings wants the MEST-103, which ships in shelf packs of 5.
12) How many Don-Jo MEST-103 strikes come in a pack?
The MEST-103 ships in shelf packs of 5. If you are standardizing strikes across a floor or a building, order in multiples of five and you will not end up with a partial pack sitting on the shelf. For a single door repair you are still buying the five.
