Don-Jo EST-175-630 – Frequently Asked Questions

1) Will the Don-Jo EST-175 fit a standard ASA strike prep in my frame?
The EST-175 is an ASA-format extended lip strike measuring 4-7/8 inches by 1-3/4 inches, so it drops into a frame already prepped for a standard 4-7/8 inch ASA (T-strike) cutout. The critical number is the 1-3/4 inch dimension: that is measured from the center of the screw hole to the end of the lip, not overall plate width. Measure that same way on the strike you are pulling out before you order.
2) Why would I use an extended lip strike instead of a standard ASA strike?
An extended lip carries the latch further out past the frame face so the bolt rides over the stop and any built-out trim or thick casing instead of catching on it. That is the fix when a door closes but the latch drags or scars the jamb, or when the frame sits proud of the wall. On a flush hollow metal frame with nothing in the bolt's path, a plain-lip ASA strike does the same job. The EST-175 is the extended lip version, with the lip measured 1-3/4 inches from the screw hole center.
3) Does the EST-175 strike work for a deadbolt as well as the latch?
No. The EST-175 has a single latch hole, so it accepts one bolt, the latch. A door with a separate deadbolt above the lockset needs its own deadbolt strike or a combination strike with two openings. If you are replacing a two-hole strike, this is not a like-for-like swap.
4) What strike should I use on a pair of doors where there is no frame to mortise into?
The Don-Jo EST-175 is an extended lip ASA strike, which needs a jamb or frame to receive it, so it is the wrong part for the meeting stile of a pair. For a double door opening, the Detex 92 Strike Kit is built for double door applications and comes with tamper resistant fasteners, which is what you want on an exposed inactive leaf. It is part of the Detex 90 Strike Series. Keep the EST-175 for the single door frames in the same building and use the 92 kit at the pairs.
5) Will an ASA strike work on a round pipe or tube frame?
No. The Don-Jo EST-175 is a flat 4-7/8" x 1-3/4" extended lip ASA strike cut for a standard flat jamb face. A round pipe or tube post needs a strike made to sit on that curve, and the Trimco 1260P is a pipe adapter strike sold as the strike only. Order the EST-175 for flat hollow metal or wood jambs and the 1260P where the latch lands on pipe.
6) Is the Don-Jo EST-175 strong enough for a high traffic commercial entrance?
It is built from 13-gauge (.095) steel and specified for commercial use, which is the weight you want behind a latch that gets hit hundreds of times a day in an office, school, or hospital corridor. Thin residential stamped strikes deform at the lip; 13-gauge does not. It handles the latch bolt only, so on a door that also carries a deadbolt you will need a separate strike for that bolt.
7) Can I use the EST-175 on a round post or pipe rather than a door frame?
No. The EST-175 is a flat ASA strike sized 4-7/8 x 1-3/4 inches for a prepped door frame. Latching into a round column or pipe is what the Trimco 1260P Pipe Adapter Strike is built for. Wrong shape of substrate, wrong strike.
8) Is the Detex 92 strike kit a drop-in replacement for a Don-Jo EST-175?
They are not interchangeable. The EST-175 is a single extended lip ASA strike with one latch hole in 13-gauge (.095) steel, finished DU, 622 or 630, sold for standard commercial frames. The Detex 92 is a strike kit for double door openings, supplied with tamper resistant fasteners in the Detex 90 Strike Series. If you are replacing a damaged ASA strike in an existing frame prep, stay with the EST-175; the 92 kit addresses a different opening condition.
9) I need to standardize strikes across a facility that has flat jambs, pipe posts and pairs. What do I stock?
Three parts cover it. The Don-Jo EST-175 extended lip ASA strike handles the flat commercial jambs, and because it is offered in DU, 622 and 630 you can match it to whatever trim finish is already on those doors. The Trimco 1260P pipe adapter strike, from the 1260 Series, covers latches that land on pipe or tube. The Detex 92 Strike Kit, in the 90 Strike Series, covers the double door openings and brings tamper resistant fasteners for the exposed locations. Stocking all three by opening type is cleaner than trying to force one strike onto every condition.
10) What finishes does the Don-Jo EST-175 ASA strike come in?
Three: 630 satin stainless steel, 622 matte black, and DU duronodic brown coated. 630 is the usual match for satin stainless commercial lever trim and hollow metal openings, 622 for black hardware packages, and DU for dark bronze anodized aluminum storefront and older commercial doors. Pick the one already on your levers and closers so the jamb does not read as a repair.
11) I manage a building and need to standardize strikes across a lot of doors. Is the EST-175 sold in bulk?
Don-Jo packs the EST-175 in shelf packs of 10, which suits stocking a maintenance shop or working through a floor of openings in one visit. Since all three finishes share the same 4-7/8 x 1-3/4 inch ASA body, you can standardize the strike across the building and vary only the finish to match each opening's existing hardware.
12) Does the Don-Jo EST-175 strike have a hand, and does the lip direction matter?
The strike body itself is symmetrical top to bottom, but the lip projects toward the side the door swings from, so it has to face the correct way for the latch to ride onto it. Mount it with the lip running toward the stop side of the frame in the direction the latch approaches. Confirm the swing at the opening before you fasten it; an inverted lip will not guide the bolt.
