Don-Jo EST-125-630 – Frequently Asked Questions

1) Will the Don-Jo EST-125 fit a standard ASA strike prep in my frame?
The EST-125 is an extended lip ASA strike measuring 4-7/8 inches by 2-1/2 inches, so it drops into the standard 4-7/8 inch ASA (T-strike) frame cutout used on commercial hollow metal frames. Read the 2-1/2 inch figure carefully: it is measured from the center of the screw hole out to the end of the lip, not the overall face width of a normal strike. That is the number that tells you how far the lip reaches past the frame.
2) When do I need an extended lip strike instead of a standard ASA strike?
Use an extended lip strike like the EST-125 when the frame sits back from the face of the door stop or trim, or when the jamb is wrapped in drywall or a return that the latch would otherwise ride across. The longer lip carries the latch across that gap so it slides onto the strike instead of catching the frame edge or chewing the finish. On a flush hollow metal frame where the door face lines up with the strike face, a standard lip ASA strike is the right part and the extended lip just sticks out further than you need. Measure from the center of the strike screw holes to where you need the lip to end, and compare it to the 2-1/2 inch dimension.
3) Will the EST-125 work for a pair of doors with no mullion?
No. The EST-125 is a single latch hole ASA strike, so it handles one latchbolt on one frame jamb. For a pair of doors where the inactive leaf carries the strike, look at a double door strike kit such as the Detex 92 Strike Kit, which is built for double door applications and ships with tamper resistant fasteners.
4) How thick is the steel on the Don-Jo EST-125 strike?
13-gauge, which is .095 inch steel. That is heavier than the light strike plates packed with most residential locksets, and it is why this one is spec'd for high traffic openings, schools, healthcare, and multi-tenant buildings where a strike takes constant abuse and pry attempts.
5) What finishes does the Don-Jo EST-125 extended lip strike come in?
Three: 630 satin stainless steel, 622 matte black, and DU duronodic brown coated. If you are matching existing hardware across a building, 630 is the usual pairing with satin stainless levers and exit devices, DU is the match for dark bronze aluminum storefront and entrance hardware, and 622 pairs with matte black trim.
6) Is the Don-Jo EST-125 a deadbolt strike or a latch strike?
Latch. It has a single latch hole, cut for one latchbolt, so it serves a cylindrical or mortise latch on one opening. It is not a two-hole strike for a lockset with both a latch and a separate deadbolt, and it is not a deadbolt-only strike.
7) I need a strike for a pipe or round post frame, will this one work?
No, the EST-125 has a flat ASA face and mounts to a flat jamb. For a round post or pipe frame you need a strike shaped to the curve, such as the Trimco 1260P pipe adapter strike from the 1260 Series, which is sold as the strike only.
8) How many strikes come in a pack of the Don-Jo EST-125?
They ship in shelf packs of five. For a property manager or contractor doing a whole floor of openings, that means ordering one pack covers five doors; a single door repair still buys the pack of five.
