Don-Jo D9125-630 – Frequently Asked Questions

1) What size is the Don-Jo D9125 extended lip strike, and how is the 2-1/2 inch width measured?
The D9125 measures 2-1/4 inches in height by 2-1/2 inches in width, and the width is not the full plate face. It is measured from the center of the screw hole out to the end of the extended lip. That matters when you are checking clearance against the door stop, because the lip is what carries out past the frame face toward the door. Measure your existing strike the same way before you compare numbers.
2) What is an extended lip strike for, and do I need one instead of a standard strike?
An extended lip is for openings where the frame sits back from the door face, or where trim or a thick stop leaves the latch travelling past the plate before it seats. The longer lip carries the latch across that gap so it rides into the pocket instead of catching on the frame edge. If your latch already engages cleanly on a flush frame, a standard lip strike does the job and the extra lip on the D9125 just projects further into the opening. The deciding measurement is the 2-1/2 inches from screw hole center to lip end.
3) Will the Don-Jo D9125 work on a pair of doors with no mullion?
No. The D9125 is a single lip strike sized 2-1/4 by 2-1/2 inches, made to mount in a frame jamb and receive one latch. A pair of doors meeting at the center has no jamb to mount it in. For a double door you want a purpose-built double-door strike kit, such as the Detex 92 Strike Kit from the 90 Strike Series, which is made for that condition and comes with tamper resistant fasteners.
4) What is the difference between a Trimco 1260P pipe adapter strike and a Don-Jo D9125 extended lip dimple strike?
They solve different openings. The Trimco 1260P from the 1260 Series is a pipe adapter strike, supplied as the strike only, and it is intended to adapt a latch to a pipe or tubular frame member. The Don-Jo D9125 is a conventional extended lip dimple strike measuring 2-1/4 inches high by 2-1/2 inches wide, with the width taken from the center of the screw hole to the end of the lip, in 18-gauge (.050) steel. On a standard commercial frame the D9125 is the flat strike to specify; the 1260P applies where the strike has to land on pipe rather than on a flat jamb face.
5) Is the Detex 92 strike kit a substitute for a Don-Jo D9125 extended lip dimple strike?
No. The Don-Jo D9125 is an extended lip dimple strike, a flat strike plate that mounts in the frame or door edge and seats the latch bolt in a dimpled latch hole. The Detex 92 Strike Kit is a double door strike kit from the 90 Strike Series and is supplied with tamper resistant fasteners, so it is built for the meeting stile of a pair of doors rather than for a single latch in a frame. If the opening is a pair of doors being fitted with Detex hardware, the 92 kit is the part; for a single latch strike in a commercial frame, the D9125 is the direct part.
6) What does the dimple on the Don-Jo D9125 strike actually do?
The dimple is a formed depression at the latch hole that gives the latch bolt a defined seat rather than a flat opening. The bolt drops into the dimple and stays put, which keeps the door from rattling in the frame and reduces the latch face wear you get when a bolt is riding the edge of a plain punched hole. On high-cycle openings that is the difference between a door that stays quiet and one that needs adjusting.
7) Is 18-gauge steel heavy enough for a strike on a high-traffic commercial door?
18-gauge (.050) steel is the commercial-grade material on the D9125, and it is what you want on doors that cycle constantly, schools, offices, healthcare corridors, warehouse and multi-tenant entries. A strike is backed by the frame, so its job is to resist the latch hammering the same spot thousands of times rather than to span an unsupported area. Thinner residential stampings deform at the latch hole first; the heavier gauge here holds the dimple shape.
8) What finishes does the Don-Jo D9125 strike come in for matching existing door hardware?
Four finishes: 605 polished brass, 622 matte black, 630 satin stainless steel, and DU duronodic brown. For a building standardizing on stainless lever hardware, 630 is the match; 605 pairs with polished brass lock trim, and DU is the dark bronze anodized look common on aluminum storefront and older commercial frames. If you are replacing strikes across a fleet of doors, match the finish to the lockset rather than the frame paint, since the strike sits alongside the latch face.
9) Is the D9125 strike handed, or does one part work on both left and right hand doors?
The D9125 is a symmetrical rectangular lip strike, so there is no left or right version to specify. Order the finish and the size; the lip orientation is set by which jamb you mount it in, not by the part. That is one less thing to get wrong when you are ordering strikes for a mixed run of openings.
10) Do I need to modify the frame to install a Don-Jo extended lip strike?
That depends on what is in the frame now. The D9125 mounts with screws through the plate and needs a pocket behind the latch hole for the bolt to enter. If you are replacing a strike of the same 2-1/4 inch height, the existing screw holes and latch pocket usually carry over and it is a straight swap. Going from a shorter or non-lipped strike to this one means the plate outline and the lip projection change, so plan on filing the mortise and, on a wood frame, plugging and redrilling screw holes.
11) For a single commercial door with a standard latch, which strike should be ordered instead of a double door kit or a pipe adapter strike?
The Don-Jo D9125 extended lip dimple strike is the one that fits that description. It is a commercial 18-gauge (.050) steel strike with an extended lip and a dimpled latch hole, sized 2-1/4 inches by 2-1/2 inches, and it comes in 605 polished brass, 622 matte black, 630 satin stainless steel and DU duronodic brown to match the rest of the trim on the opening. The Detex 92 Strike Kit is a double door kit in the 90 Strike Series, and the Trimco 1260P is a pipe adapter strike, so neither addresses a single latch striking a flat jamb.
12) Can I buy the D9125 strike in bulk for a multi-door retrofit?
The D9125 is packed in shelf packs of 10, which suits a floor or a building section rather than a single door swap. Property managers rekeying or re-latching a run of units generally order by pack and keep the remainder as spares, since strikes are the part that gets bent or lost during frame work.
