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

1) Will a Don-Jo EL-103 extended lip strike cover the gap where my frame sits back from the door?
That's what the extended lip is for. The EL-103 measures 2-1/4 inches in height and 3 inches in width, with the width taken from the center of the screw hole to the end of the lip. That center-to-lip figure is the number that matters: it tells you how far the lip reaches past the mounting holes to carry the latch across the gap and off the frame face. Measure from where the strike screws land to where you need the lip to end. If 3 inches from screw center gets you past your jamb reveal, the EL-103 covers it.
2) Can I use the Don-Jo EL-103 with a deadbolt as well as a latch?
No. The EL-103 has a single latch hole, so it accepts one bolt, the latchbolt from a knob or lever set. For a door with a separate deadbolt above the lockset you need a second strike for that bolt, or a combination strike with two openings. Ordering the EL-103 for a two-bolt door leaves you a strike short.
3) What is the difference between an extended lip strike and a pipe adapter strike or a double door strike kit?
Three different jobs. An extended lip strike like the Don-Jo EL-103 is a flat plate with a long lip that carries a latchbolt across a wide gap on a standard frame. The Trimco 1260P pipe adapter strike mounts a strike to round pipe rather than a flat jamb, which is what you need on a gate or a pipe post. The Detex 92 Strike Kit from the 90 Strike Series is for double doors and ships with tamper resistant fasteners, aimed at exit device applications on a pair. If your problem is a jamb reveal that leaves the latch short, the extended lip is the one; if the problem is the substrate or a pair of doors, it isn't.
4) Will the Don-Jo EL-103 fit the existing strike cutout in my hollow metal frame?
Check two things against your prep. The plate face is 2-1/4 by 3 inches, and the 3 inch figure runs from screw hole center out to the lip end, so the portion sitting in the frame pocket is shorter than 3 inches. Second, corner profile: order the radius corner version if your frame is prepped with rounded pocket corners, square if not. Match those and it drops in on the existing screw pattern.
5) Is the Detex 92 strike kit an alternative to a Don-Jo EL-103 extended lip strike?
They solve different problems. The Don-Jo EL-103 is an extended lip strike measuring 2-1/4 inches high by 3 inches wide, formed from 18-gauge (.050) steel with one latch hole, so it mortises into the frame and catches a single latch. The Detex 92 Strike Kit is a double door strike kit from the Detex 90 Strike Series and ships with tamper resistant fasteners, so it is built for a pair of doors rather than a single latch point. If you are replacing a lipped strike on one leaf of a commercial opening, the EL-103 is the direct part; if you are strike-prepping a double door assembly, the 92 kit is the one that matches that condition.
6) What strike should I use instead of an extended lip strike when the latch has to catch on a pipe or round post?
The Don-Jo EL-103 is a flat extended lip strike sized 2-1/4 inches by 3 inches for a conventional flat frame face, and it will not sit correctly against a curved surface. For that opening the Trimco 1260P from the Trimco 1260 Series is a pipe adapter strike, supplied as the strike only, and is the part shaped for a pipe or round-post condition. Keep the EL-103 for the standard hollow metal or wood frames elsewhere in the same job.
7) Square corners or radius corners on a replacement door strike, how do I know which one I need?
Look at the strike that's in the frame now, or at the cutout itself. Hollow metal frames are routinely prepped with a radiused pocket, and a square corner strike won't drop into it cleanly. The EL-103 is offered with optional radius corners for exactly that reason, so match the corner profile to the existing prep rather than trying to file a square plate to fit. If you're cutting fresh prep, either works.
8) Is 18 gauge steel heavy enough for a strike on a high traffic commercial door?
The EL-103 is 18-gauge steel at .050 thickness, which is the commercial standard for a lip strike and holds up in office buildings, schools, healthcare, retail, and multi-tenant residential where doors cycle all day. The lip is the part that takes abuse, since the latch rides across it every close, and .050 steel resists the curling and deformation you get from thinner residential stock.
9) What finishes does the Don-Jo EL-103 extended lip strike come in?
Eight, and they cover the usual commercial specs: 605 bright brass, 609 antique brass, 619 satin nickel, 620 antique nickel, 622 matte black, 629 bright stainless, 630 satin stainless, and DU duronodic brown coated. For matching a fleet of doors, 630 satin stainless is the standard commercial pairing with satin chrome hardware, and 605 pairs with polished brass trim.
10) My exterior pair of doors keeps failing to latch, is an extended lip strike the fix?
Only if the latch is reaching the frame but not seating because the strike sits too far back. An extended lip strike gives the bolt a longer ramp and a deeper pocket to catch. If instead the doors are a pair with exit devices and the trouble is at the meeting stile or the fasteners are being attacked, look at a double door strike kit like the Detex 92, which comes with tamper resistant fasteners. Diagnose which of the two you have before ordering, because the extended lip does nothing for a meeting stile problem.
11) If I need tamper resistant fasteners at the strike, does the Don-Jo EL-103 cover that?
The Don-Jo EL-103 is specified as an 18-gauge (.050) steel extended lip strike with a single latch hole, offered in DU, 605, 609, 619, 620, 622, 629 and 630 finishes and with optional radius corners, and it is ordered as the strike itself. Where the requirement on the drawing is specifically for tamper resistant fasteners at the strike, the Detex 92 Strike Kit is supplied with tamper resistant fasteners as part of the kit, on a double door application in the Detex 90 Strike Series. Match the part to which requirement is driving the spec: lip projection and frame finish, or fastener security on a pair of doors.
12) Do I have to buy a case of strikes or can I get just one?
The EL-103 is packed in a shelf pack of 10. That suits a property manager standardizing a run of doors or a contractor prepping a floor of openings, since you get the same finish across every frame in one order rather than chasing dye lots later.
13) Is the Don-Jo EL-103 a strike plate or a strike box?
It's the plate. The EL-103 is an extended lip strike, a formed steel face with one latch opening and a lip that guides the bolt. There's no dust box or mortise cup included, so if your frame needs a box behind the opening you order that separately.
