Don-Jo DEST-125-DU – Frequently Asked Questions

1) Will the Don-Jo DEST-125 strike fit a standard ASA strike prep in my frame?
The DEST-125 is cut for standard ASA strike preparation, so it drops into a frame already prepped for an ASA (T-strike) cutout. It measures 4-7/8 inches in height, which is the standard ASA strike height, and the 2-1/2 inch dimension is taken from the center of the screw hole out to the end of the lip. If your frame is prepped for a 4-7/8 x 1-1/4 ASA strike, the hole pattern lines up and only the lip runs longer.
2) What is an extended lip strike for, and do I need one instead of a standard ASA strike?
An extended lip is for openings where the door sits back from the frame face, or where there is a deep reveal, trim, or stop that the latch has to ride over before it reaches the strike. The lip carries the latchbolt across that gap so it does not catch on the frame edge or the casing. On the DEST-125 the lip runs out to 2-1/2 inches measured from the center of the screw hole. If your latch already lands cleanly on a standard short-lip ASA strike, you do not need the extended version. Measure from the screw hole centerline to where the door face stops, and the lip has to reach past it.
3) Can I use the DEST-125 to replace a worn or bent strike on an existing commercial door without redoing the frame?
Yes, if the frame is already ASA prepped. The DEST-125 uses the standard ASA cutout and 4-7/8 inch height, so a like-for-like swap is a two-screw job with no cutting. What changes is the lip length, which runs 2-1/2 inches from the screw hole centerline. Going from a short lip to this extended lip is fine, it just projects further out over the frame face. Going the other direction, replacing an extended lip with this one, check that the old lip was not longer still or the latch may sit short of the ramp.
4) What strike should I use on a pair of double doors instead of the Don-Jo DEST-125?
The DEST-125 is an extended lip dimple ASA strike sized 4-7/8 inches by 2-1/2 inches for a standard ASA strike prep in a single-door frame, so on a pair of doors where the latch catches the inactive leaf rather than the frame, look at the Detex 92 Strike Kit for double doors, which is supplied as a kit with tamper resistant fasteners and belongs to the Detex 90 Strike Series. Order the DEST-125 when the latch lands in a prepped frame jamb, and the Detex 92 kit when the strike has to be mounted for a double door opening.
5) Is the Trimco 1260P a substitute for a Don-Jo extended lip ASA strike?
No. The Trimco 1260P is a pipe adapter strike, sold as the strike only, in the Trimco 1260 Series, and it is intended for an opening where the latch engages a pipe or round post rather than a flat prepped jamb. The Don-Jo DEST-125 is an extended lip dimple ASA strike measuring 4-7/8 inches by 2-1/2 inches, cut for a standard ASA strike preparation in a flat frame. They mount to different substrates, so one does not drop into the other's opening.
6) Is the Don-Jo DEST-125 strong enough for a high-traffic commercial entry?
It is 18-gauge (.050) steel and built for commercial use, which is the gauge you want on an opening that gets cycled all day, school corridors, office suites, healthcare, retail back-of-house. On a strike, gauge is what resists the lip deforming when the latch slams into it repeatedly. For an opening that is being attacked rather than just used hard, a strike plate alone is not the fix, you want the frame reinforced behind it.
7) What finishes does the Don-Jo DEST-125 come in, and which one matches my existing hardware?
Three finishes: 622 matte black, 630 satin stainless steel, and DU duronodic brown coated. 630 is the one to pick if the rest of the opening is satin stainless or brushed chrome, which covers most commercial lever and exit hardware. 622 matte black pairs with black lever trim and storefront. DU duronodic is the dark bronze look used on anodized aluminum entrances, so match it to the door frame rather than to the lockset.
8) Can I standardize on one strike across all the doors in my building?
If the openings are ASA prepped, yes, and that is the usual reason a facility buys these by the box. The DEST-125 is one part number in one of three finishes covering every ASA prepped frame in the building. Where it will not standardize: aluminum storefront and glass front openings often use a different strike entirely, and double doors without a mullion need a double door kit like the Detex 92. Walk the building and sort openings by prep first, not by door.
9) Is the DEST-125 a strike plate only, or does it include a strike box and screws?
The DEST-125 is the strike plate itself, the 18-gauge steel face that mounts to the jamb. If your frame has no dust box behind the cutout, or the old box is crushed, order a strike box separately. Same for security fasteners if the opening needs tamper resistant screws, a double door kit like the Detex 92 comes with those, a plain ASA strike does not.
10) What is the dimple on a dimple ASA strike and does it change how the door latches?
The dimple is the raised or recessed detail on the strike face that the latchbolt or auxiliary deadlatch plunger rides on. On a lock with an auxiliary deadlatch it keeps that small plunger from dropping into the strike opening, which is what keeps the latch deadlocked when the door is closed. If your lockset has a deadlatch plunger beside the main latch, a dimple strike is the correct type, not a plain flat ASA strike.
11) The latch on my gate hits a round post, not a frame - can I use the DEST-125 there?
The DEST-125 is a commercial extended lip dimple ASA strike with a 4-7/8 inch by 2-1/2 inch flat body made for a standard ASA prep, so it needs a flat jamb face to seat against. For a latch landing on a pipe or round post, the Trimco 1260P pipe adapter strike from the Trimco 1260 Series is the part built for that condition, and it is sold as the strike by itself.
12) I need a strike with security fasteners for a high-abuse opening - what are my options against the DEST-125?
The Don-Jo DEST-125 is an 18-gauge (.050) steel extended lip dimple ASA strike offered in DU, 622 and 630 finishes, and it installs with the screws your frame prep takes. If the requirement is fastener security on a double door opening, the Detex 92 Strike Kit is furnished with tamper resistant fasteners as part of the kit in the Detex 90 Strike Series. Choose by opening type first: the DEST-125 for an ASA-prepped single door frame, the Detex 92 kit where a double door strike with tamper resistant fasteners is being specified.
