Don-Jo ETS-104-630 – Frequently Asked Questions

1) What size is the Don-Jo ETS-104 T strike and how is the 4 inch measured?
The ETS-104 measures 2-3/4 inches in height by 4 inches in width, and the width is taken from the center of the screw hole to the end of the lip, not edge to edge. That matters when you are checking clearance to the stop: the extended lip runs out past the screw line toward the door, so measure your existing strike the same way before you assume it drops in. It has a single latch hole.
2) What is an extended lip strike for, and do I need one instead of a standard T strike?
An extended lip strike like the Don-Jo ETS-104 is what you use when the door is set back from the frame face, or there is heavy trim or a thick applied stop, and a standard lip is too short to carry the latch across the gap. The longer lip guides the latchbolt over that reveal and protects the wood or trim from being chewed up by the latch. If your latch already engages cleanly and the door face sits close to the frame, a standard length lip strike is the simpler part. Measure from the center of your screw line to where the latch actually rides, and match it to the 4 inch dimension on the ETS-104.
3) Will the ETS-104 work on a pair of doors with no mullion?
No. The ETS-104 is a single latch hole strike, meant to be mounted in the frame jamb for one latchbolt. A pair of doors without a mullion needs a strike made for that condition, such as the Detex 92 Strike Kit for double doors, which comes with tamper resistant fasteners and is part of the Detex 90 Strike Series. Use the ETS-104 on a single door in a frame.
4) Will the Don-Jo ETS-104 fit a deadbolt as well as the latch?
One hole only. The ETS-104 has a single latch hole, so it takes the latchbolt from a knob or lever set, not a latch and a deadbolt together. For an opening with both a lockset and a separate deadbolt you either need two strikes or a T strike with a second cutout.
5) What is the difference between a Trimco 1260P pipe adapter strike and a Don-Jo ETS-104 T strike?
They solve different framing problems. The ETS-104 is an extended lip T strike, 2-3/4 inches high by 4 inches wide with a single latch hole, made from 18-gauge non-ferrous material for commercial door use, and it mounts to a conventional jamb face. The Trimco 1260P from the 1260 series is a pipe adapter strike supplied as the strike only, intended for adapting the latch point to a pipe or tubular frame condition. A locksmith replacing a worn strike in an existing flat jamb prep is looking at the ETS-104; a pipe or round-post frame is what sends you to the 1260P instead.
6) Is the Detex 92 strike kit an equivalent replacement for a Don-Jo ETS-104 extended lip T strike?
No. The ETS-104 is an extended lip T strike in 18-gauge non-ferrous material with a single latch hole, sized 2-3/4 inches high by 4 inches wide with the width taken from the center of the screw hole to the end of the lip, and it prepares one leaf for a standard latch bolt. The Detex 92 strike kit is a double door strike kit from the 90 strike series supplied with tamper resistant fasteners, so it addresses the pair of doors and the fastener security question rather than dropping into a single-door T strike prep. Use the ETS-104 where you are replacing or extending the lip on a single strike prep, and specify the Detex 92 kit when the opening is a double door and you want tamper resistant fasteners.
7) Is the Don-Jo ETS-104 strike heavy enough for a high traffic commercial opening?
It is an 18-gauge (.050) commercial strike, non-ferrous. That is the working thickness for a commercial latch strike rather than a light residential stamping, and non-ferrous means it will not rust out on exterior or damp openings like a plated steel strike will. Don-Jo rates it for commercial use, so it suits office, school, healthcare, retail, warehouse and multi-tenant residential doors.
8) What finishes does the Don-Jo ETS-104 extended lip strike come in?
Five: 605 polished brass, 609 antique brass, 622 matte black, 630 satin stainless, and DU duronodic brown coated. If you are matching an existing opening, 630 is the one that lines up with most modern commercial lever and exit hardware, and DU is the match for dark bronze storefront and aluminum entrance hardware. 622 matte black is the one to pick against black anodized or black powder coated trim.
9) Does the Don-Jo ETS-104 come with a strike box or dust box?
The ETS-104 is the strike plate itself, an 18-gauge non-ferrous extended lip T strike with a single latch hole. If the frame behind your existing strike has no pocket, or the old dust box is crushed, order a strike box separately. In a hollow metal frame with an existing cutout you usually already have the pocket and only need the plate.
10) For a double door opening in a school corridor, should I order the Don-Jo ETS-104 or the Detex 92 strike kit?
Order by what the opening needs at the meeting point. The Detex 92 is a double door strike kit in the 90 strike series and comes with tamper resistant fasteners, which is the answer when the strike sits where students can reach the screw heads on a pair of doors. The Don-Jo ETS-104 is a single latch hole extended lip T strike in 18-gauge non-ferrous material, specified for commercial openings including educational facilities, and it is the part for a single strike location where the lip needs to extend to meet the latch. Facilities standardizing across a building often carry both: the ETS-104 for the single-leaf corridor and office doors, the Detex 92 kit for the paired entrances.
11) I need a strike in a specific architectural finish to match existing hardware. Which of these gives me finish options?
The Don-Jo ETS-104 extended lip T strike is offered in 605 polished brass, 609 antique brass, 622 matte black, 630 satin stainless steel, and DU duronodic brown coated, so it can be matched to brass, black, stainless, or bronze-tone hardware already on the doors. The Detex 92 double door strike kit and the Trimco 1260P pipe adapter strike are each defined by their configuration rather than a finish range in the same way, the 92 as a double door kit with tamper resistant fasteners and the 1260P as a pipe adapter strike sold as the strike only. When the deciding factor is coordinating appearance across a run of openings, the ETS-104 finish range is the one to work from.
12) I am standardizing strikes across a building. How is the Don-Jo ETS-104 packed?
It ships in shelf packs of 10, which is why it works for a re-strike program across a floor or a whole property rather than a one-off door. Order one finish per opening group and you can carry a single part number for every door on that hardware set. All five finishes are the same 2-3/4 by 4 inch body.
