Kwikset KWI-85063 Radius Corner Deadbolt Strike

The 85063 is a radius corner deadbolt strike, so the plate corners are rounded to match a frame pocket that was routed with a router bit rather than chiseled square. If the existing pocket in your jamb has square corners, a square corner strike like the Emtek 83223 seats without recutting; dropping a radius plate into a square pocket leaves visible gaps at the four corners.

The 85063 is a residential-duty deadbolt strike. It is the right part for apartment unit doors, single family entries, and light multi-family work. For a commercial opening, particularly anything on a hollow metal frame or a fire rated door, you want a commercial grade strike specified with the lock rather than a residential replacement plate.

Deadbolt only. The 85063 is built for the bolt pocket of a deadbolt, not for a spring latch, and it has no curved lip to ride a latch back as the door closes. If you are replacing the plate under a knob or lever latch you need a latch strike, not this one.

Both are deadbolt strike plates. The Deltana SP2753 is a steel deadbolt strike measuring 2-3/4 inches by 1-1/4 inches, so you can check that footprint against the mortise you already have. The Kwikset 85063 is a radius corner strike in steel and comes in Bright Brass, Satin Chrome, Satin Nickel and Dark Bronze/Black. Measure the existing plate and match the corner profile before ordering either.

Steel is the substrate on the 85063, with the finish applied over it. That matters for a deadbolt strike more than for a latch strike, because the bolt drives straight into the plate edge under a kick and a plated steel plate takes that load better than a solid decorative brass one.

No. The 85063 is the strike plate on its own, the piece that mortises into the jamb and receives the bolt. If the deadbolt itself throws and keys fine and only the jamb plate is damaged, painted shut, or the wrong finish, this replaces it without touching the lock.

Two other deadbolt strikes to look at. The Emtek 83223 is a standard deadbolt strike with square corners, for a chiseled square pocket. The Deltana SP2753 is a 2-3/4 by 1-1/4 inch steel deadbolt strike, useful when you need a known plate footprint to compare against what is cut in your jamb.

The Kwikset 85063 radius corner deadbolt strike is offered in Bright Brass, Satin Chrome, Satin Nickel and Dark Bronze/Black. For a deadbolt strike outside that group, the Deltana SP2753 is a 2-3/4 inch by 1-1/4 inch steel deadbolt strike, and the Emtek 83223 is a standard deadbolt strike plate with square corners. Confirm the corner profile of the jamb mortise before switching, since a square corner plate will not seat in a radius routed mortise without rework.

The Kwikset 85063 is a steel deadbolt strike specified for residential use. Where a project calls for a stainless steel strike, the Codelocks ASA strike plate is supplied in a stainless steel finish, though it is an ASA-format strike for a latching lock rather than a deadbolt strike, so the two are not interchangeable in the same jamb prep.

For a fleet of residential deadbolts, the Kwikset 85063 radius corner deadbolt strike covers four finishes from one part number, which keeps a single SKU across doors that differ only in trim color. Where a run of doors was prepped with square corner mortises, the Emtek 83223 standard deadbolt strike plate carries square corners for that prep. Survey the corner shape on a sample of jambs first, since that determines how many part numbers the building actually needs.
