Don-Jo ETS-103-630 – Frequently Asked Questions

1) Will the Don-Jo ETS-103 T strike cover a latch that no longer lines up with the frame prep?
That is what the extended lip is for. The ETS-103 is an extended lip T strike measuring 2-3/4 inches in height by 3 inches in width, with the width taken from the center of the screw hole out to the end of the lip. That extra lip reach past the screw centerline is what catches a latch sitting proud of a worn or offset frame prep, so the door still pulls up and latches instead of bouncing. It has a single latch hole, so it suits one standard latchbolt, not a lock with a separate deadbolt hole.
2) How do I know the 3-inch width on a Don-Jo ETS-103 strike is measured the way I think it is?
It is not the overall face width in the usual sense. On the ETS-103 the 3 inches runs from the center of the screw hole to the end of the lip, and the 2-3/4 inches is the height. Measure your existing strike the same way before you order, because a strike sold as 3 inches wide overall will give you a shorter lip reach than this one.
3) Will a Don-Jo ETS-103 work on a pair of doors or on an exit device?
No. The ETS-103 is a single latch hole strike for a standard latchbolt on a single opening. For a double door with exit devices you want a purpose-built double door strike kit such as the Detex 92 Strike Kit, which comes with tamper resistant fasteners and is part of Detex's 90 Strike Series. Different job entirely, different prep.
4) What strike should be used on a double door with a vertical rod exit device instead of a Don-Jo ETS-103?
The ETS-103 is an extended lip T strike sized 2-3/4 inches high by 3 inches wide, made for capturing a single latch on a standard frame, and it has one latch hole. A pair of doors running an exit device is a different opening: the Detex 92 Strike Kit is a double door strike kit from the Detex 90 Strike Series and ships with tamper resistant fasteners, which is the direction to go when the strike lands on the meeting stile of a pair rather than on a hinge-side frame. Use the ETS-103 where a lockset latch throws into a frame, and the Detex 92 kit where a double door assembly needs its own strike hardware.
5) Will an extended lip T strike work where the latch throws into a pipe or tubular frame member?
The Don-Jo ETS-103 is a flat extended lip T strike with a single latch hole, dimensioned 2-3/4 inches by 3 inches with the width taken from the center of the screw hole to the end of the lip, so it wants a flat frame face to seat and screw against. A round or tubular member is not that surface. The Trimco 1260P is a pipe adapter strike from the Trimco 1260 Series and is sold as the strike only, which is the part to specify when the strike has to adapt to a pipe rather than sit flat on a jamb.
6) Is an 18-gauge non-ferrous strike heavy enough for a high-traffic commercial door?
The ETS-103 is built from 18-gauge (.050) non-ferrous stock and is a commercial-rated strike, which is the weight of material a door strike needs to take repeated latching without deforming at the lip. Non-ferrous also means it will not rust out, so it holds up on exterior openings, healthcare corridors, and washdown-prone areas where a plated steel strike streaks.
7) What finishes does the Don-Jo ETS-103 T strike come in, and which one matches my existing lever finish?
Five: 605 polished brass, 609 antique brass, 622 matte black, 630 satin stainless steel, and DU duronodic brown coated. Those are standard BHMA finish numbers, so if your levers or closers are marked 626 or 630 you are in satin territory and 630 is the match; 605 pairs with bright brass trim, 609 with the darker antique brass, and DU with the dark bronze anodized aluminum storefront look.
8) I manage a building with dozens of doors that no longer latch cleanly. Can I standardize on one strike?
For openings with a single latchbolt and a misaligned or offset latch condition, the ETS-103 is the same part every time, in one of five finishes. It is a commercial extended lip T strike, so a maintenance crew can carry one finish and work through a floor. Where a door has a separate deadbolt as well as a latch, this one will not cover it: the ETS-103 has one latch hole only.
9) What is the difference between a T strike and a full lip strike or an ANSI strike?
A T strike gets its name from the shape: a narrow body with a wider lip section, so it drops into a frame prepped for a T-shaped cutout rather than the tall rectangular ANSI 4-7/8 inch prep. The Don-Jo ETS-103 is the extended lip version, meaning the lip runs further out from the screw centerline to reach a latch that sits proud of the frame. If your frame is already prepped for a 4-7/8 inch ANSI strike, this is not the part; if you are replacing an existing T strike and the latch is not being captured, it is.
10) I have a hollow metal frame with a pipe or tube column instead of a flat jamb. Is the ETS-103 the right strike?
Not for a round column. The ETS-103 is a flat-mount extended lip T strike. Where the latch has to land on pipe or tube, the Trimco 1260P Pipe Adapter Strike from the 1260 Series is the part made for that condition. Use the ETS-103 on a conventional flat jamb where the latch is missing the existing strike.
11) Is the Detex 92 strike kit a drop-in replacement for a Don-Jo ETS-103 on a single commercial door?
No. The ETS-103 is a single-piece extended lip T strike in 18-gauge (.050) non-ferrous material, offered in 605 polished brass, 609 antique brass, 622 matte black, 630 satin stainless steel, and DU duronodic brown coated, and it addresses one latch hole. The Detex 92 is a strike kit for double doors that includes tamper resistant fasteners and belongs to the Detex 90 Strike Series. They solve different openings, and the Detex kit is not a finish-for-finish swap for a T strike on a single leaf.
12) For a facility standardizing strike hardware, which of these strikes cover which conditions?
Three conditions, three parts. For flat hinge-side frames on single doors with a conventional lockset latch, the Don-Jo ETS-103 extended lip T strike covers it, and its extended lip profile helps where the latch sits offset or slightly out of alignment. For pairs of doors, the Detex 92 Strike Kit from the 90 Strike Series is the double door answer and comes with tamper resistant fasteners for exposed locations. Where the latch has to engage a pipe section, the Trimco 1260P pipe adapter strike from the 1260 Series is the strike-only part for that adaptation. Standardizing usually means stocking the ETS-103 for the bulk of openings and pulling the other two only where the frame condition demands it.
13) How many Don-Jo ETS-103 strikes come in a pack?
The ETS-103 ships in shelf packs of 10. Worth knowing before you order for a single door repair, and it is the reason it works well as a truck-stock or project item where you are replacing strikes across a run of openings.
