Schlage A Series SCH-10-001-118 Square Corner, T-Strike With Box, 1-1/8" x 2-3/4", 1-1/8" Lip

The 10-001-118 T-strike is a replacement strike for Schlage A Series cylindrical locks, and it also fits the CS210 and S200 series. If you're replacing a strike on an A Series knob or lever set, this is the matching part. It won't be the right strike for a mortise lock or a deadbolt, since those use their own strike preps.

The strike plate face measures 1-1/8 by 2-3/4 inches, which is the standard T-strike footprint used on Schlage A Series cylindrical locks. If the frame is already prepped for a 1-1/8 x 2-3/4 T-strike, this drops straight in with no new mortising. If your frame carries a full-lip ASA strike (roughly 1-1/4 x 4-7/8), the cutout is larger and this plate will not cover it.

The lip is the curved tab that projects out past the frame and guides the latchbolt in as the door closes. On the 10-001-118 it measures 1-1/8 inches. Lip length has to reach past the face of the door stop and trim so the latch rides up onto it instead of catching on the frame. Measure from the centerline of the strike opening out to the outside edge of the frame or casing on the stop side; if that's about 1-1/8 inches, this lip is right. Deeper trim or a frame set proud of the jamb wants a longer lip.

The 10-001-118 is a square corner strike, so it suits a frame prepped with square corners, which is typical of hollow metal and standard commercial frames. Wood frames routed with a template often have rounded (radius) corners instead. Look at the existing cutout: square corners take this plate flat, radius corners will leave gaps at the four corners and want a radius-corner strike instead.

Yes, the box comes with the strike. That's the metal cup that sits behind the plate in the frame and catches the latchbolt, so you're not ordering it separately. On a frame that already has a box in good shape you can reuse it, but having the matching one avoids a mismatch between the plate opening and the pocket behind it.

Nine finishes: 605 bright brass, 606 satin brass, 609 antique brass, 612 satin bronze, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, 625 bright chrome and 626 satin chrome. Order the strike in the same BHMA finish number as the lockset on the door, since the plate sits at eye level on the frame and a mismatch shows. For a fleet of openings, 626 satin chrome and 630 stainless are the usual commercial standards, and 626 is available here.

Yes. The 10-001-118 is a replacement strike, so if the lock itself is fine and only the strike is bent, worn at the lip, or missing, you swap the plate and box and leave the A Series, CS210 or S200 lockset in the door. Two screws in the frame is the whole job as long as the existing cutout is the 1-1/8 x 2-3/4 square corner prep.

Across openings running Schlage A Series, CS210 or S200 cylindrical locks, the 10-001-118 is the one strike to stock, provided the frames are prepped square corner at 1-1/8 x 2-3/4 and the trim depth suits a 1-1/8 inch lip. Pick a single finish (626 satin chrome is the usual choice for a mixed commercial building) and one part number covers the fleet. Openings with mortise locks or exit devices are outside that, they take their own strikes.

It's a commercial-duty part, built in stainless steel rather than plated pot metal, which matters on a strike because it takes the impact every time the door closes and the shear load on any push against the latch. That construction is what suits it to apartment corridors, offices and other openings cycling all day.
