Schlage Commercial K510-066 Strike Box, 1-1/4" x 4-7/8"

The K510-066 is the metal cup that sits behind a strike plate, inside the mortised pocket in the frame, so the latch or deadbolt drops into a lined box instead of a raw hole in the jamb. It's a Schlage commercial replacement part, sized 1-1/4 x 4-7/8 inches. If you're chasing a hole in the frame that's chewed up, or you pulled an old lock and the box came out with it, this is the piece that goes back in behind the plate.

Yes. The K510-066 is built for ANSI strike prep, which is the 1-1/4 by 4-7/8 inch cutout used on commercial hollow metal frames. If your frame is already prepped to ANSI, the box drops in. If you're working on a residential frame with the small 1-1/8 x 2-3/4 T-strike prep, this is the wrong part, the pocket won't take it.

Yes. The K510-066 is the box alone, the lining behind the face. The visible strike plate that screws to the jamb is a separate part. If your existing plate is in good shape you can reuse it over this box; if the plate is bent or the wrong finish, order an ANSI strike plate to match.

It is, provided the frames carry ANSI strike prep, which is standard on commercial hollow metal. The K510-066 is a commercial part, not a residential one, and at 1-1/4 x 4-7/8 inches it matches the ANSI pocket. That makes it consistent across a fleet of openings, one box for every frame prepped the same way. Confirm one frame with a tape measure before ordering for the whole building.

Genuine. The K510-066 is a certified Schlage commercial part, ordered by that model number. For an MRO or institutional buyer standardizing a facility on Schlage hardware, that matters, the part number is what you put on the requisition and it keeps the frames consistent.

On many Schlage parts it does, and Schlage flags them as finish specific. The strike box itself sits behind the plate and out of sight once installed, so the visible finish call is on the plate rather than the box. Match the plate to the rest of the trim on the opening.
