Kwikset 83031 UL Radius Corner Full Lip Strike

The plate measures 2-1/4 x 1-5/8 inches with a 1-1/8 inch lip. Measure your current strike before ordering: if the old plate is larger in either direction, the 83031 will not cover the old mortise and you will see bare wood around it. The 1-1/8 inch lip dimension is the part that matters on the jamb face, since the lip wraps the edge of the frame and guides the bolt in.

It's a deadbolt strike. The 83031 receives the square deadbolt throw, not a beveled spring latch, so it's the jamb-side plate for a single or double cylinder deadbolt. If you're replacing the strike for a knob or lever latch, this is the wrong plate for that hole.

Both are deadbolt strike plates, but they differ in corner style. The Kwikset 83031 is a radius corner full lip strike, so its corners are rounded to match a jamb mortise cut by a router or a factory-prepped jamb. The Emtek 83223 is a standard deadbolt strike plate with square corners, which suits a jamb chiseled square by hand. Cut the mortise to match the corner style you order, or square the corners of a routed pocket if you are fitting a square-corner plate.

The Kwikset 83031 faceplate measures 2-1/4 inches by 1-5/8 inches with a 1-1/8 inch lip. If the existing mortise in the jamb is longer than that, the Deltana SP2753 is a steel deadbolt strike plate measuring 2-3/4 inches by 1-1/4 inches, so it covers more jamb height and less width. Measure the existing cutout in both directions before choosing, since a plate narrower than the old pocket will leave the mortise edges exposed.

They are not interchangeable. The Kwikset 83031 is a deadbolt strike plate sized 2-1/4 inches by 1-5/8 inches with a 1-1/8 inch lip, cut for a residential deadbolt bolt. The Codelocks ASA Strike Plate in stainless steel follows the ASA strike format, a larger commercial-pattern plate used with ASA-prepped frames. Swapping one for the other means recutting the jamb, so match the plate to the prep already in the frame.

The 83031 is a UL listed strike, which is why it carries the UL designation in its name. Beyond the listing itself, no specific fire door rating attaches to the strike as a standalone part, and the rating on any opening comes from the door, frame, and lock assembly as a whole. For a rated opening, match the strike to whatever the door and lock manufacturer's labelled assembly calls for.

Three finishes: Satin Chrome, Satin Nickel, and Dark Bronze/Black. For a fleet of doors, match the strike to the deadbolt's finish family rather than to the door: Satin Nickel next to a satin nickel or 15 style deadbolt, Satin Chrome next to brushed chrome, and Dark Bronze/Black next to a venetian bronze or matte black bolt. The strike sits on the jamb and reads against the lock, so a mismatch there is the visible one.

Full lip means the plate extends over the jamb edge, which protects the frame from the bolt scraping it and helps guide a slightly misaligned bolt home. That's what the 83031 gives you. A T strike or a box strike is the alternative when the jamb face is too narrow for a lip, or when the mortise pocket already there won't accept the extra wrap. On a standard residential wood jamb replacement, the full lip is the common choice.

Kwikset lists the 83031 as a residential strike, which puts it in single family, small multi family, and light apartment turnover work rather than a Grade 1 commercial opening. For a commercial frame, particularly a hollow metal jamb with an ASA prep, the Codelocks ASA strike plate in stainless is the format that fits that cutout. The 83031 is the wrong shape for an ASA prep.

Both are deadbolt strikes, but the footprints differ. The 83031 measures 2-1/4 x 1-5/8 inches with a 1-1/8 inch lip and has radius corners. The Deltana SP2753 is a 2-3/4 x 1-1/4 inch steel deadbolt strike. If your existing mortise is longer than 2-1/4 inches, the taller Deltana plate is the one that covers it; if the pocket is short and routed round, the Kwikset drops in without chisel work.

A binding bolt is usually alignment, not the plate. Before swapping, throw the bolt with the door open and mark where it lands on the jamb. If the mark sits above or below the strike hole, the door has settled and the fix is repositioning the strike or shimming the hinges, not a new plate. Where the 83031 does help is when the old plate is chewed, the lip is torn, or the bolt is dragging the raw jamb edge on the way in, since the full lip covers that edge and gives the bolt a clean ramp.

No. The Kwikset 83031 is a full lip strike, meaning the plate extends past the face of the plate and wraps over the edge of the door frame to guide the bolt and protect the jamb edge. A flat plate without that extension sits only in the mortise face. If you are replacing a Kwikset 83031, confirm the replacement has the lip, because a flat plate will leave the jamb edge unprotected where the old lip covered it.

No single plate covers both, so plan by prep type. The Kwikset 83031 is the radius corner full lip deadbolt strike and it is offered in Satin Chrome, Satin Nickel, and Dark Bronze/Black, so one part number can carry across differing door finishes. For openings whose jambs are chiseled square, the Emtek 83223 standard deadbolt strike plate has square corners. Survey the jambs first, then order by corner style and keep the finish consistent across both.

Yes, both are deadbolt strike plates. The Deltana SP2753 is a steel deadbolt strike plate at 2-3/4 inches by 1-1/4 inches, and the Kwikset 83031 is a UL-listed radius corner full lip deadbolt strike at 2-1/4 inches by 1-5/8 inches with a 1-1/8 inch lip. The decision comes down to the mortise footprint in your jamb and whether the opening calls for a UL-listed strike.

The 83031 is the strike plate itself, not a lockset or a latch mechanism. If you're doing a security upgrade on a residential entry, plan on 3 inch screws that reach past the jamb into the stud framing, since the short screws that ship with most strikes only bite the jamb. Reusing the existing screw holes is fine when the new plate lines up with the old ones.
