Kwikset KWI-85278 1-1/8" x 2-3/4" Square Corner Deadbolt Strike

The Emtek 83223 standard deadbolt strike plate is the closest like-for-like part. Both are deadbolt strike plates with square corners, so a square-corner mortise already routed in the jamb for the Kwikset 85278 takes the Emtek 83223 without changing the cutout shape. Confirm the finish family you need matches what is already on the door, since the Kwikset 85278 runs in Bright Brass, Satin Nickel, Satin Chrome, Dark Bronze/Black and Antique Nickel.

Five finishes: Bright Brass, Satin Nickel, Satin Chrome, Dark Bronze/Black, and Antique Nickel. That is the full range, so a landlord or property manager standardizing on one look across a building can match the strikes to the deadbolts already hung on the other doors.

Residential. The 85278 is a residential-duty steel deadbolt strike, which suits apartments, single-family rentals, and light multi-family doors. For a commercial entrance taking heavy daily traffic, spec a commercial-grade strike rather than this one.

No. The 85278 is a strike plate on its own, the jamb-side piece the bolt throws into, and it can be replaced without touching the deadbolt in the door. Pull the two screws, swap the plate, and check the bolt throws fully into the opening without binding on the plate edge.

For a fleet of residential doors, the Kwikset 85278 and the Emtek 83223 both cover the standard square corner deadbolt prep, so either can be the single stocked plate where the jambs are routed square. The Deltana SP2753 is the one to hold separately, since its 2-3/4 inch by 1-1/4 inch face is wider than the 1-1/8 inch by 2-3/4 inch Kwikset and suits doors cut to the wider mortise. The Codelocks ASA plate serves the ASA strike pattern and belongs to a different prep entirely.

A deadbolt strike catches the square throw of a deadbolt and has no lip to ride the latch, so it is not a substitute for a latch strike. The Kwikset 85278, the Deltana SP2753 and the Emtek 83223 are all deadbolt strike plates. Order against the bolt in the door, not the handle set, since the plate is sized to the bolt pocket.

Steel, then plated to the finish you order. Steel is what you want behind a deadbolt: the plate is the part a kick loads against, and a solid brass decorative plate deforms sooner. Note that the plate alone is not a reinforced box strike, so on an exterior door the screws still need to reach the framing behind the jamb to do any real good.

Yes, the 85278 is sold as the strike plate by itself. That is the usual buy for a property manager replacing bent or painted-over strikes across a building, or a locksmith carrying spares in the van, without the cost of a full deadbolt for each door.
