Schlage Commercial 10-072 Strike w/Box, L Series, 1-1/4" x 4-7/8"

Lip length is the main ordering decision on the 10-072, and it depends on how far the strike sits from the face of the stop. Six choices are offered: 7/8, 1, 1-3/16 (the standard), 1-1/2, 1-3/4, and 2 inches. Measure from the centerline of the strike opening out to the point where the door face lands, then pick the lip that carries the latch clear of the frame without projecting past the door face. If you are matching an existing L Series mortise opening, 1-3/16 inch is the standard and is what most jobs take.

The 10-072 is a square corner strike with a face measuring 1-1/4 x 4-7/8 inches, which is the standard mortise lock strike prep. If your frame is cut square (not radius corner) and the existing plate measures 1-1/4 by 4-7/8, this drops straight in with no filing. Radius corner preps will need the corners dressed or a radius strike instead. It ships with the box, so you are not reusing the old dust box.

Yes, that is exactly what it is for. The 10-072 is an L Series mortise lock strike, not a cylindrical lock strike. If you are working on a Schlage ND, AL or B Series bored lock, this is the wrong part, those take a smaller cylindrical strike. Check the lock case first: a mortise lock is a rectangular case mortised into the door edge, and it is what this 1-1/4 by 4-7/8 inch plate is prepped for.

The box is included. That matters on a retrofit where the old dust box is rusted, crushed by an over-throwing bolt, or missing from a frame that was never boxed properly. You get the square corner strike plate and the box together, so the deadbolt and latch both have somewhere clean to land.

Nine finishes are offered on the 10-072 strike: 605 bright brass, 606 satin brass, 609 antique brass, 612 satin bronze, 613 oil rubbed bronze, 622 matte black, 625 bright chrome, 626 satin chrome, and 643E aged bronze. Those are BHMA finish numbers, so order the strike in the same number stamped on your existing Schlage lock trim and it will match across the opening. For a building standardizing on one look, 626 satin chrome and 613 oil rubbed bronze are the two that cover most commercial and multi-family specs.

The strike itself is a flat square corner plate, so bevel is handled at the latch, not here. Schlage A Series latches adjust for either flat or beveled edge doors, so the geometry at the door edge is taken up by the latch while the 10-072 stays in its standard 1-1/4 by 4-7/8 inch frame prep. What you do need to get right on a beveled opening is lip length, because the bevel changes where the door face lands relative to the strike.

If the latch catches on the frame edge before it reaches the strike opening, a longer lip is the fix, it carries the ramp out toward the door face so the latch rides up and in. Going the other way, a lip that projects past the door face and snags sleeves or carts means you want a shorter one. The 10-072 covers 7/8 inch through 2 inches in six steps, so you can step up or down without changing the frame prep, which stays 1-1/4 by 4-7/8.

Yes, the 10-072 is sold as a replacement part on its own. A worn, bent, or mismatched strike is a common cause of a door that will not latch, and swapping it is a screwdriver job against the existing frame prep as long as that prep is square cornered and 1-1/4 by 4-7/8 inches. For a property manager with a run of L Series openings, buying strikes and lips separately from the lock bodies is how you keep the fleet consistent without pulling working locks.

The substrate is stainless steel, which is what you want in a strike that takes a latch impact every cycle and, on an exterior opening, takes weather through the gap. Stainless resists the corrosion that eats a plated steel strike at the lip edge where the finish wears through first. For a commercial application, this is a commercial rated part, not a residential one.
