Don-Jo MEST-175-DU – Frequently Asked Questions

1) Will the Don-Jo MEST-175 fit a standard ASA strike prep in my frame?
Yes. The MEST-175 is an extended lip ASA strike measuring 4-7/8 inches by 1-3/4 inches, which is the standard ASA (T-strike) face size used on commercial hollow metal frames. If your frame is already prepped for a 4-7/8 inch ASA strike, this drops into the same cutout and screw pattern.
2) What does the 1-3/4 inch dimension on the MEST-175 actually measure?
It is not the overall plate width in the usual sense. On the MEST-175 the 1-3/4 inch figure is measured from the center of the screw hole out to the end of the extended lip, so it tells you how far the lip projects past the frame face toward the door stop. The 4-7/8 inch figure is the height of the strike.
3) Does the MEST-175 have a hole for a deadbolt as well as the latch?
No. The MEST-175 is a single latch hole strike, so it catches the latchbolt only. If the opening has a separate deadbolt above the lockset, you need a second strike or a combination strike prepped for both bolts.
4) Is the Trimco 1260P a substitute for the Don-Jo MEST-175 ASA strike?
No. The Don-Jo MEST-175 is an extended lip ASA strike, 4-7/8 inches high by 1-3/4 inches wide in 13-gauge non-ferrous material, mortised into the frame to catch a standard latch. The Trimco 1260P is a pipe adapter strike, supplied as the strike only in the 1260 Series, and is intended for a pipe-adapter application rather than a standard ASA frame prep. If the frame is prepped for a 4-7/8 inch ASA strike, the MEST-175 is the part that matches that cutout.
5) For a double door with an exit device, should I order the Don-Jo MEST-175 or the Detex 92 strike kit?
They address different openings. The Detex 92 Strike Kit is a double door strike kit in the 90 Strike Series and ships with tamper resistant fasteners, so it suits a pair of doors where the strike mounts to the inactive leaf or mullion. The Don-Jo MEST-175 is a single-latch-hole extended lip ASA strike for a standard 4-7/8 inch frame prep on a single door or an active leaf with an ASA cutout.
6) Why would I use an extended lip strike instead of a standard ASA strike?
An extended lip carries the latch past a deep or wide trim condition so the bolt does not drag on the frame, the jamb, or an applied casing. If the door is set back from the frame face, a standard lip lets the latch catch on the edge instead of riding into the pocket. The MEST-175 gives you 1-3/4 inches from the screw hole centerline to the lip end for that reach.
7) Is the Don-Jo MEST-175 strong enough for a high-traffic commercial door?
It is built to 13-gauge (.095) thickness and rated by Don-Jo for commercial use, which is heavier than the light stamped strikes that come packed with residential latchsets. It is used on office buildings, schools, healthcare, retail, warehouse, multi-tenant residential, and government openings.
8) Will the MEST-175 rust on an exterior or wash-down opening?
The MEST-175 substrate is non-ferrous, so the base metal itself does not rust the way a plated steel strike will. That makes it a reasonable pick for exterior entries, coastal sites, pool areas, and kitchens where a steel strike would bleed through the finish.
9) What finishes does the Don-Jo MEST-175 come in, and will they match my existing lever hardware?
Three: 622 matte black, 630 satin stainless steel, and DU duronodic brown coated. 630 is the standard commercial finish and matches most satin stainless levers and exit devices; 622 pairs with matte black trim; DU matches dark bronze anodized aluminum storefront and entrance hardware.
10) Can I use the Don-Jo MEST-175 on a pair of doors with no mullion?
Not for the inactive leaf. The MEST-175 is a frame-mounted ASA strike for a single latch on a jamb. For a double door application you would be looking at something like the Detex 92 Strike Kit, which is a double door strike kit supplied with tamper resistant fasteners.
11) I need a strike for a pipe or tube jamb, not a hollow metal frame. Will this work?
An ASA strike like the MEST-175 is cut for a flat jamb face and will not sit properly on a round section. For that condition look at the Trimco 1260P pipe adapter strike, which is made for a pipe jamb.
12) I need tamper resistant fasteners on a strike. Does the Don-Jo MEST-175 offer that?
Tamper resistant fasteners are called out on the Detex 92 Strike Kit for double doors. The Don-Jo MEST-175 is specified on the strength of its material and gauge instead: 13-gauge (.095) non-ferrous construction that resists corrosion and holds its finish, offered in matte black, satin stainless steel, and Duronodic brown coated for commercial openings.
13) Is the MEST-175 sold individually or in a box?
It ships as a shelf pack of 5 units. That works in your favor if you are standardizing strikes across a building or restocking a service van, but it means a single-door repair leaves you with spares.
