Don-Jo EL-125-630 – Frequently Asked Questions

1) What size is the Don-Jo EL-125 extended lip strike, and how is the lip length measured?
The EL-125 measures 2-1/4 inches in height and 2-1/2 inches in width. The width figure is the one people get wrong: it's taken from the center of the screw hole out to the end of the lip, not the overall plate width. So when you're checking whether the lip will reach across a gap between the frame and the door face, measure from where your screw line lands, not from the edge of the strike.
2) Why would I use an extended lip strike instead of a standard ANSI strike?
An extended lip strike like the EL-125 is what you reach for when the door sits back from the frame face, or the jamb is thick enough that a standard lip leaves the latch dragging on the wood or hitting a raw edge. The longer lip carries the latch across that gap and gives it a ramp to ride on. If your door closes flush against a normal jamb with no setback, a standard strike is the simpler part. The EL-125's lip reach is 2-1/2 inches from the screw hole centerline, so measure your setback against that number before committing.
3) Will the Don-Jo EL-125 work with a deadbolt as well as a latch?
No. The EL-125 has a single latch hole, so it accepts one bolt only. If you have a lockset with both a latch and a deadbolt, or a separate deadbolt above the lock, you need a second strike for the deadbolt or a two-hole strike. Ordering the EL-125 for a double-bolt opening means cutting a second prep or coming back with another part.
4) Do I need square or radius corners on my strike, and does the EL-125 come both ways?
That's decided by your existing frame prep, not by preference. Hollow metal frames are commonly prepped with a radiused cutout, and dropping a square-corner strike into one leaves gaps at the corners; a wood jamb chiseled square wants square corners. The EL-125 is offered with radius corners as an option, so pull the old strike first, look at the cutout, and match it. Getting this wrong means chiseling or filing the frame on site.
5) What strike should I use on a pair of doors where there is no frame jamb to mount the EL-125 into?
The Don-Jo EL-125 is an extended lip strike, meaning it mounts into the frame jamb and its lip carries the latch across the gap to the door. On a pair of doors there is no jamb on the active-leaf side, so a jamb-mounted lip strike has nothing to land on. For that opening, look at the Detex 92 Strike Kit, which is a double door strike kit from the 90 Strike Series and ships with tamper resistant fasteners. That fastener detail matters on exterior pairs and on stairwell and exit pairs in schools and multi-tenant buildings, where an exposed strike is a target. Keep the EL-125 for single-leaf openings in a hollow metal or wood jamb, where the 2-1/4 inch by 2-1/2 inch extended lip is doing the job it was cut for.
6) Is the Trimco 1260P the same kind of strike as a Don-Jo EL-125?
No. The Trimco 1260P is a pipe adapter strike from the 1260 Series, sold as the strike only, and it is made to adapt a latch to a round pipe frame rather than to a flat jamb face. The Don-Jo EL-125 is an extended lip strike for standard flat frame prep, 2-1/4 inch high by 2-1/2 inch wide, in 18 gauge steel. The two are not interchangeable: order the 1260P when the frame is pipe or tubular, and the EL-125 when you are replacing or extending a conventional flat-jamb strike. Distributors ordering blind off a description should treat pipe adapter and extended lip as two separate part families, not two names for the same plate.
7) Is the Don-Jo EL-125 strong enough for a high traffic commercial door?
The EL-125 is 18-gauge (.050) steel and is a commercial-rated part, not a residential one. That gauge is what keeps the lip from deforming when a latch is being slammed into it a few hundred times a day in an office corridor, school, or hospital wing. For apartment and multi-tenant common doors it's the same story: the strike is usually the first thing to bend, and 18 gauge holds up better than the thin stamped strikes that come in the box with a residential lockset.
8) Can I use the Don-Jo EL-125 on a pair of doors with no mullion?
No, and this is worth catching before you order. The EL-125 is a lip strike that mounts to a jamb, so it needs a frame member to screw into. On a double door with an active and inactive leaf, the strike has to mount to the inactive leaf edge and that's a different part. For a double door application, look at a kit built for it such as the Detex 92 Strike Kit for double doors, which comes with tamper resistant fasteners.
9) What's the difference between the Don-Jo EL-125 and a pipe adapter strike?
They solve different openings. The EL-125 is a flat lip strike for a conventional jamb, 18-gauge steel with a single latch hole. A pipe adapter strike, like the Trimco 1260P from the 1260 Series, is shaped to mount against a round post or tube rather than a flat frame face, which is what you hit on some glass front and storefront installs. If your latch is landing on a pipe or tube column, the EL-125 won't sit flat against it.
10) For a facility standardizing its strike stock, which of these covers the most openings?
The Don-Jo EL-125 covers the broadest slice of ordinary single-door work: an extended lip strike in 18 gauge steel, 2-1/4 inch by 2-1/2 inch, sold in shelf packs of 10 and available in eight finishes including 605 polished brass, 619 satin nickel, 622 matte black and 630 satin stainless, so one part number can be matched to whatever is already hanging in the building. The other two are opening-specific rather than general stock: the Detex 92 Strike Kit is a double door kit from the 90 Strike Series with tamper resistant fasteners, and the Trimco 1260P from the 1260 Series is a pipe adapter strike sold as the strike only. A sensible MRO shelf carries the EL-125 in the house finish for day-to-day single doors and brings in the other two per opening.
11) What finishes does the Don-Jo EL-125 extended lip strike come in?
Eight finishes, and they cover most of what you'd already have on a commercial opening: 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're matching existing hardware across a building, 630 satin stainless is the usual commercial standard and 622 matte black the common modern spec. Order the same finish code as the lever or closer trim already on the door and it'll disappear into the jamb.
12) How many Don-Jo EL-125 strikes come in a pack?
The EL-125 is sold in shelf packs of 10. That suits the way this part actually gets bought: a property manager restriking a floor of units, a locksmith stocking a van, or a maintenance shop keeping spares on the shelf. If you only need one opening fixed, you're still buying ten, so it's worth standardizing the whole building on one finish.
