Don-Jo DT9125-630 – Frequently Asked Questions

1) What size is the Don-Jo DT9125 T-strike, and how is the width measured?
The DT9125 measures 2-3/4 inches in height by 2-1/2 inches in width, and the width is taken from the center of the screw hole out to the end of the extended lip, not across the face of the strike. That matters when you are laying out frame prep: the lip run is what has to clear the stop and reach the door face, so measure from your existing screw centerline before you cut.
2) What does the extended lip on a Don-Jo DT9125 strike actually do for me?
An extended lip carries the latch further past the frame face, so the bolt rides up onto the lip instead of catching the edge of the jamb. You use it where the door is set back from the frame face, where a wide casing or trim stands proud of the jamb, or where the existing lip is chewing up the door edge. The DT9125 lip runs out to the 2-1/2 inch width measured from the screw hole center.
3) What is a dimple strike and will my latch work with it?
The dimple is a shallow recess pressed into the strike behind the latch hole, so the latch bolt seats into the dimple rather than into an open box cutout. It works with standard latch bolt configurations found in commercial locksets, which is what the DT9125 is built around. If your frame currently has a deep strike box behind it, the dimple face is not a replacement for that box, it is the strike plate itself.
4) Is the Don-Jo DT9125 the right strike for a pair of doors with no mullion?
No. The DT9125 is a single jamb-mounted latch strike for a standard commercial opening. For a double door where the strike has to be picked up off the inactive leaf or off the header, look at the Detex 92 Strike Kit, which is the double door strike kit in the Detex 90 Strike Series and comes with tamper resistant fasteners.
5) Is the Detex 92 strike kit an equivalent replacement for a Don-Jo DT9125 extended lip dimple T-strike?
No - they solve different problems. The Don-Jo DT9125 is an extended lip dimple T-strike, a single flat frame strike measuring 2-3/4 inches high by 2-1/2 inches wide in 18-gauge (.050) steel, with the width taken from the center of the screw hole to the end of the lip. It receives the latch bolt of a standard commercial lockset in one frame or door edge. The Detex 92 Strike Kit is a double door strike kit supplied with tamper resistant fasteners and belongs to the Detex 90 Strike Series, so it is aimed at a pair of doors and an exit device application rather than at replacing a latch strike in a single frame. If a locksmith is matching an existing latch strike cutout, the DT9125 is the T-strike profile; the Detex kit is not a drop-in for that prep.
6) When would a locksmith use a Trimco 1260P pipe adapter strike instead of a Don-Jo DT9125 T-strike?
The two suit different frame conditions. The Trimco 1260P is a pipe adapter strike from the Trimco 1260 Series, sold as the strike only, and is intended for openings where the strike has to adapt to a pipe or tubular frame member rather than seat flat in a hollow metal or wood jamb. The Don-Jo DT9125 is an extended lip dimple T-strike, 2-3/4 inches by 2-1/2 inches in 18-gauge (.050) steel, with the extended lip giving added coverage across the jamb face and secure latch engagement on a conventional commercial frame. On a standard commercial jamb taking a lockset latch bolt, the DT9125 is the T-strike to prep for; on a pipe or rail-style frame, the 1260P is the adapter form.
7) Is 18-gauge steel heavy enough for a strike on a high traffic commercial door?
18-gauge is .050 inch steel, and that is the working thickness Don-Jo uses on the DT9125 for commercial door hardware. It is a formed steel plate, not a light stamped residential strike. On high cycle openings, the thing that fails first is usually the frame prep or the screw anchorage rather than the plate, so pick up the frame with long screws into the stud or anchor behind the jamb.
8) What finishes does the Don-Jo DT9125 strike come in?
Four finishes: 605 polished brass, 622 matte black, 630 satin stainless steel, and DU duronodic brown coated. For matching a building's existing openings, 630 is the one that lines up with the satin stainless and brushed chrome hardware most commercial jobs are standardized on, and DU is the one to pull if the frames are the dark bronze anodized aluminum you see on storefront entries.
9) I only need one or two strikes. How is the DT9125 sold?
The DT9125 ships as a shelf pack of 10 strikes. It is packaged for contractors and distributors running multiple doors at once, so if you are chasing a single opening you will still be buying the ten pack. On the other hand, a box of ten in one finish is the cheap way to standardize a floor of offices or a corridor of unit doors on the same strike.
10) Do I need a T-strike or a full lip strike for my door frame?
A T-strike is the shape you use where the strike has to sit in a narrower jamb face and the latch tongue extends out on its own leg, giving you the T profile. It is the common replacement shape on hollow metal and aluminum commercial frames. If your frame is prepped for a rectangular ANSI strike, that is a different cutout and a T-strike will not cover it. Match the shape of the hole that is already in the jamb before you match anything else.
11) Can I use a DT9125 strike on a pipe or round post frame?
Not a fit. The DT9125 is a flat plate strike meant to land on a flat jamb face. When the latch has to catch on round tube, a gate post, or pipe, you want a strike made for that curve, such as the Trimco 1260P pipe adapter strike from the 1260 Series, which is sold as the strike only.
12) For a property manager standardizing latch strikes across a building, which of these strikes actually covers multiple doors at once?
The Don-Jo DT9125 extended lip dimple T-strike is a commercial single-opening strike sold in a shelf pack of 10 and offered in 605 polished brass, 622 matte black, 630 satin stainless steel, and DU duronodic brown coated, so one finish choice can be repeated door to door across a floor or a building. The Detex 92 Strike Kit is scoped to a double door opening and comes with tamper resistant fasteners, which makes it a fix for a specific pair of doors rather than a fleet-wide latch strike, and the Trimco 1260P is a pipe adapter strike supplied as the strike only for pipe-frame conditions. For repeating the same latch strike across many conventional commercial jambs, the DT9125 is the one with the finish range and the pack quantity to do it.
13) Will one strike finish work across an office, a school corridor, and a warehouse door?
Yes, and that is the usual play for a facility standardizing hardware. The DT9125 is a commercial-grade strike used across office buildings, educational and healthcare facilities, retail, industrial and warehouse space, multi-tenant residential, and government buildings. Buy the ten pack in 630 satin stainless and you can carry one strike on the truck for every opening in the portfolio that takes this prep.
