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

1) Will the Don-Jo MEST-104 fit a standard ASA strike prep in my frame?
The MEST-104 is cut to the ASA (T-strike) footprint at 4-7/8 by 4 inches, so it drops into an existing ASA strike prep without new frame cutting. The 4-inch dimension is measured from the center of the screw hole out to the end of the lip, not the plate face, so an extended lip strike like this one covers more of the jamb than a standard-lip ASA plate of the same 4-7/8 length. If your frame is already prepped for a standard 4-7/8 x 1-1/4 ASA strike, the mounting holes line up and the extra material sits out past the jamb face.
2) Why would I use an extended lip strike instead of a standard ASA strike?
An extended lip is what you reach for when the door is set back from the jamb face, when there is heavy trim or a deep reveal, or when the latch is scarring the frame on the way in. The lip carries the latchbolt past the obstruction and rides it into the pocket. The MEST-104 gives you 4 inches from the screw hole center out to the lip end, so measure from your existing strike screw line to where the latch actually needs to be picked up. If that distance is short, a standard lip ASA strike is the cheaper and cleaner install; the extended lip only earns its keep when there is something for the latch to clear.
3) Does the Don-Jo MEST-104 work with a deadbolt as well as the latch?
No. The MEST-104 has a single latch hole, so it accepts one bolt only. If you have a lockset with a latchbolt and a separate deadbolt above it, you need a two-hole strike or a separate deadbolt strike for the upper bolt. A mortise lock with a latch and deadbolt in one case also wants a two-hole ASA strike, not this one.
4) Can I use the MEST-104 on a pair of doors with no mullion?
Not as-is. The MEST-104 is a single-latch ASA strike that mounts to a frame jamb, so it serves one leaf latching into a frame or mullion. For a double door where both leaves need to latch to each other, look at a purpose-built double-door strike such as the Detex 92 Strike Kit, which is made for double door applications and comes with tamper resistant fasteners.
5) What is the difference between a Trimco 1260P pipe adapter strike and a Don-Jo MEST-104 extended lip strike?
They mount to different things. The Trimco 1260P is a pipe adapter strike from the 1260 Series, sold as a strike only, and it is meant for an opening where the latch has to land on a pipe or round post rather than a flat frame face. The Don-Jo MEST-104 is a flat extended lip ASA strike, 4-7/8 inches by 4 inches, 13-gauge non-ferrous, with a single latch hole and an extended lip that reaches out to capture the latch on a standard commercial frame. For a gate or a rail with a round upright, the 1260P is the adapter that suits it. For a hollow metal or wood frame with an ASA prep, the MEST-104 is the strike that matches the prep.
6) Will a Detex 92 strike kit work in place of a Don-Jo MEST-104 ASA strike?
No, they solve different openings. The MEST-104 is an extended lip ASA strike with a single latch hole, made from non-ferrous 13-gauge material and sized 4-7/8 inches high by 4 inches wide, with that width taken from the center of the screw hole to the end of the lip. It drops into a standard ASA strike prep in a single door frame. The Detex 92 Strike Kit is part of the 90 Strike Series and is built for double door applications, and it ships with tamper resistant fasteners. If the opening is a pair of doors being fitted to a Detex exit device, the 92 kit is the part to look at; if it is a single door with an ASA prep where the latch needs a longer lip reach, the MEST-104 is the one that fits the prep.
7) Is the Don-Jo MEST-104 strike heavy enough for a high-traffic commercial door?
It is 13-gauge (.095) material, which is the heavy end for a face-applied strike and thick enough to take repeated latch strikes on an entry that cycles all day. Don-Jo rates the MEST-104 for commercial use. On a school corridor, a hospital wing, or a multi-tenant lobby door, gauge is what keeps the lip from deforming and throwing the latch out of alignment over time.
8) Will the MEST-104 strike rust on an exterior or coastal door?
The MEST-104 is made from non-ferrous material, so there is no steel to rust through at the lip where water sits. That makes it a reasonable choice on exterior openings, pool and locker room doors, coastal buildings, and washdown areas where a plated steel strike blisters and streaks the frame within a season.
9) Does the Don-Jo MEST-104 extended lip strike have a handing, and do I need to specify left or right?
There is no handing to call out on the MEST-104, and no left or right version to order. The only thing you choose is finish. What does matter on an extended lip strike is which way the lip faces once installed, so mount it with the lip running out over the stop side the latch approaches from.
10) What finishes does the Don-Jo MEST-104 strike come in, and which one matches my existing hardware?
Three finishes: 622 matte black, 630 satin stainless steel, and DU duronodic brown coated. For a building already standardized on 630 satin stainless levers and closers, which is the most common commercial spec, take the 630 and it will read as the same family. 622 matte black pairs with black storefront and modern black lever trim; DU duronodic is the dark bronze anodized look used on older aluminum storefront and bronze entry systems.
11) A frame has a corroding steel strike near a pool deck and the maintenance crew wants a direct swap. Which strike suits it?
The Don-Jo MEST-104 is the one built for that condition. It is a commercial extended lip ASA strike in non-ferrous 13-gauge material, which is the reason to reach for it in a wet or chemically aggressive area, and it comes in 622 matte black, 630 satin stainless steel, and DU duronodic brown coated so it can be matched to whatever else is on the doors. It fits a standard ASA prep with a single latch hole, so on a frame already prepped for ASA it is a swap rather than a re-prep. The other two comparable strikes do not cover this opening the same way: the Detex 92 Strike Kit is a double door kit in the 90 Strike Series, and the Trimco 1260P is a pipe adapter strike from the 1260 Series.
12) I need strikes for a whole building. How is the Don-Jo MEST-104 packaged?
The MEST-104 ships in shelf packs of 5. For a property manager or MRO buyer standardizing openings across a floor or a portfolio, that means ordering in fives per finish, and it is worth pulling one pack of the finish you use most for the truck or the shop shelf.
