Don-Jo EL-175-630 – Frequently Asked Questions

1) What does the Don-Jo EL-175 extended lip strike measure, and how is the lip length measured?
The EL-175 measures 2-1/4 inches in height by 1-3/4 inches in width. The width figure is the one that trips people up: it is taken from the center of the screw hole to the end of the lip, not the overall plate width. So when you are checking whether the lip will reach past your frame face and stop, measure from your existing screw hole center out, not edge to edge.
2) Why would I use an extended lip strike instead of a standard ANSI strike on a commercial door?
An extended lip strike is what you reach for when the frame sits proud of the door stop or there is a deep reveal, and the latch would otherwise drag or chew the jamb on the way in. The extended lip carries the latch across that gap and lands it in the strike. The EL-175 gives you 1-3/4 inches from the screw hole center to the lip end for exactly that condition. If your latch already enters clean on a flush frame, a standard lip strike does the job and you do not need the extra reach.
3) How many latch holes does the EL-175 strike have, and will it work with a deadbolt too?
One latch hole, sized for a standard latch bolt. That makes the EL-175 a single-point strike for a latchset or a passage/entry lockset. If your opening has both a latch and a separate deadbolt above it, you need either a two-hole strike or a second strike plate for the bolt. Do not try to make one hole serve both.
4) I need a strike for a pair of doors with no mullion, not a single door. Will the EL-175 work?
No. The EL-175 is a lip strike that mounts in the jamb of a single door opening with one latch hole. A pair of doors with no center mullion has no jamb at the meeting stile to mount it to. For that condition look at the Detex 92 Strike Kit, a double door strike kit that ships with tamper resistant fasteners, from the Detex 90 Strike Series.
5) Will the Don-Jo EL-175 strike cover the mark left by the old strike I am removing?
Only if the old plate was 2-1/4 by 1-3/4 inches or smaller. The EL-175 is a 2-1/4 inch tall strike, which is shorter than a full ANSI 4-7/8 inch strike, so it will not hide the cutout or the paint shadow from an ANSI-prepped frame. Replacing like for like on a T-strike or small lip strike prep, it covers fine. Coming off an ANSI prep, plan on a filler plate or a full-size strike instead.
6) Is the Detex 92 strike kit an equivalent replacement for a Don-Jo EL-175 extended lip strike?
No. The Don-Jo EL-175 is a single extended lip strike, 2-1/4 inches high by 1-3/4 inches wide in 18-gauge (.050) steel with one latch hole, sold as an individual strike for a standard frame prep. The Detex 92 Strike Kit is a double door strike kit from the Detex 90 Strike Series supplied with tamper resistant fasteners. If the opening is a pair of doors being strike-kitted as a set, the Detex 92 kit is the item to order; if a single latch is dead-latching into a frame and the lip needs to reach further to the door face, the EL-175 is the part.
7) What strike should I use on a pipe or tube frame instead of a Don-Jo EL-175?
Look at the Trimco 1260P pipe adapter strike, a strike-only part from the Trimco 1260 Series made to adapt a latch to a pipe frame. The Don-Jo EL-175 is a flat extended lip strike whose 1-3/4 inch width is measured from the center of the screw hole out to the end of the lip, which suits a conventional flat frame face rather than a round pipe section. On a pipe frame the 1260P is the adapter; on a flat hollow metal or wood frame where the latch needs extra lip reach, the EL-175 covers it.
8) Does the Don-Jo EL-175 strike come with square or radius corners?
Radius corners are available on the EL-175. That matters if you are replacing a strike in a hollow metal frame that was prepped with a radius-corner cutout, because a square-corner plate will not seat in that pocket without filing. Match the corner style to what is already routed in the jamb.
9) What gauge steel is the Don-Jo EL-175 strike, and is it heavy enough for a high-traffic entry?
18-gauge steel, .050 inch thick, and it is built as a commercial strike rather than a residential one. That is the weight you want on a school corridor, a healthcare wing, a retail entry, or an apartment common door where the latch is hitting the plate hundreds of times a day. On a low-use interior door it is more plate than you need, but it will not hurt anything.
10) What finishes does the Don-Jo EL-175 strike come in?
Eight finishes on the EL-175: 605 polished brass, 609 antique brass, 619 satin nickel, 620 antique nickel, 622 matte black, 629 bright stainless, 630 satin stainless, and DU duronodic brown. If you are standardizing a building, 630 satin stainless is the usual commercial default and will sit next to most lever hardware without looking off; 622 matte black matches the current black hardware packages. Pick to the lockset already on the door, not to the frame paint.
11) Is the Don-Jo EL-175 strike sold individually or in a box?
Shelf packs of ten. That suits the way these actually get bought, a property manager re-striking a floor of doors or a contractor carrying spares on a punch list. If you only need one strike, you are still buying the pack of ten.
12) Can I use the Don-Jo EL-175 as a strike on a pipe or round post gate frame?
The EL-175 is a flat plate strike meant to fasten to a flat jamb face, so it will not sit correctly against round pipe. For a round post you want a strike made for that profile, such as the Trimco 1260P pipe adapter strike from the 1260 Series, which is sold as the strike only.
13) Does the Don-Jo EL-175 extended lip strike have handing?
The lip direction is what you have to get right. A strike lip projects toward the side the door swings from, so order and orient it to your opening's swing. The EL-175 plate itself is a simple 2-1/4 by 1-3/4 inch single-hole strike, so once the lip is facing the right way there is nothing else to hand.
14) For a security-sensitive opening, does the Don-Jo EL-175 come with tamper resistant screws like the Detex 92?
The Detex 92 Strike Kit is the one supplied with tamper resistant fasteners, and it is a double door kit in the Detex 90 Strike Series. The Don-Jo EL-175 is a single extended lip strike in 18-gauge (.050) steel with radius corners available and one latch hole, and its security contribution is the extended lip itself, which increases latch engagement over a standard lip strike. If the specification calls out tamper resistant fastening at the strike, order the Detex 92 for that pair of doors; if the requirement is deeper latch engagement on a single leaf, the EL-175 is the direct answer.
15) I need to match strike finishes across a building - which of these strikes carries a finish range?
The Don-Jo EL-175 is offered in eight finishes - DU Duronodic brown coated, 605 polished brass, 609 antique brass, 619 satin nickel, 620 antique nickel, 622 matte black, 629 bright stainless steel, and 630 satin stainless steel - so a facility standardizing strikes across mixed hardware can hold one part number and change only the finish code. The Detex 92 Strike Kit is defined by its double door configuration and tamper resistant fasteners, and the Trimco 1260P by its pipe adapter function, so those two are selected by the opening they serve rather than by finish matching.
