Emtek 83224 Standard Deadbolt Strike Plate, 1/4" Radius Corners

Both. The 83224 works with deadbolt preps at either a 2-3/8 or 2-3/4 inch backset, which are the two standard residential backsets. The backset affects where the bolt sits in the door, not the strike plate itself, so one plate covers both preps as long as the frame mortise lines up with the bolt.

Radius corners and square corners are two different jamb preps. The 83224 has 1/4 inch radius corners, so it drops into a routed mortise cut with a standard radius bit. If the existing mortise in your jamb was chiseled square, the plate will sit in it but you will see a small gap at each corner unless you square the plate seat or round the mortise corners with a chisel.

Not if the misalignment is more than a hair. The 83224 is a fixed-position plate, so it corrects nothing on its own; you would need to re-mortise the jamb. When the bolt is off by enough to bind, an adjustable strike is the better answer. Kwikset makes the 80318 full round adjustable strike and the 81825 six-way adjustable deadlatch for exactly that problem. Use the 83224 when the prep is right and you want the finish to match the rest of the hardware.

Both are deadbolt strike plates, and both are steel. The Emtek 83224 is a standard deadbolt strike with 1/4 inch radius corners, offered in twelve finishes including Oil Rubbed Bronze (US10B), Satin Nickel (US15), Flat Black (US19) and Unlacquered Brass (US3NL), so it can be matched to an existing Emtek trim set on the door. The Deltana SP2753 is a deadbolt strike plate measuring 2-3/4 inches by 1-1/4 inches. If you are matching a specific plate footprint already mortised into the jamb, work from the Deltana dimensions; if you are matching the finish of the rest of the door hardware, the Emtek finish range is the wider one.

No. The Emtek 83224 is a standard deadbolt strike plate with 1/4 inch radius corners - a fixed plate, so it will not take up misalignment between the bolt and the jamb. For that condition use the Kwikset 80318 full round adjustable strike or the Kwikset 81825 six way adjustable deadlatch, both of which are made to be adjusted to the bolt rather than requiring the bolt to meet the plate. Use the 83224 where the prep is already correct and the goal is a clean finished plate that matches the rest of the door hardware.

No. The Emtek 83224 is a residential deadbolt strike plate for tubular locks, sized to a standard residential deadbolt prep. An ASA prep is the taller commercial strike cutout and takes a plate made for it, such as the Codelocks ASA strike plate in stainless steel. If the jamb in front of you has the long commercial mortise, go to the ASA plate; the 83224 will not cover that cutout.

Twelve finishes, so you can match the plate to the deadbolt and the rest of the door hardware: Polished Brass Lifetime (US3), Unlacquered Brass (US3NL), Satin Brass (US4), French Antique (US7), Oil Rubbed Bronze (US10B), Medium Bronze (MB), Tumbled White Bronze (TWB), Polished Nickel Lifetime (US14), Satin Nickel (US15), Pewter (US15A), Flat Black (US19), and Polished Chrome (US26). For a property manager standardizing across a building, that spread lets one plate model carry every door.

The 83224 is a residential deadbolt strike. For a commercial opening on a metal frame you want a different plate; the Codelocks ASA strike plate in stainless steel is the ASA-prep option for that kind of frame.

The 83224 suits standard tubular deadbolt preps, and the prep is what matters: a 2-1/8 inch cross bore, a 1 inch edge bore, and a 2-3/8 or 2-3/4 inch backset. Any tubular deadbolt cut to that prep will throw into it. What you should check is the jamb mortise, since the plate has 1/4 inch radius corners and a fixed footprint.

If your existing plate measures 2-3/4 x 1-1/4 inches, the closest known-size match we carry is the Deltana SP2753 deadbolt strike plate in steel at those exact dimensions. Pick the Emtek 83224 instead when you are matching an Emtek deadbolt and its finish, and the jamb is prepped with radius corners.

The Emtek 83224 is the strike plate itself - the finished steel plate that mounts to the jamb face. The pocket behind it is a separate part. Kwikset sells the 81231-001 metal strike dust box and the 81640 strike box for that purpose. On new jamb prep, or where the existing bolt hole is ragged or oversized, plan on the plate plus a box; on a straight plate-for-plate swap where a box is already set in the jamb, the plate alone is usually all that is needed.

It depends on what varies. Where the deadbolt preps are consistent and the goal is one look across every door, the Emtek 83224 gives you a single plate in twelve finishes - Medium Bronze (MB), Tumbled White Bronze (TWB), Polished Nickel Lifetime (US14), Pewter (US15A), Polished Chrome (US26), Polished Brass Lifetime (US3), Satin Brass (US4) and French Antique (US7) among them - so one part number covers the building and the finish is chosen per door. Where the preps themselves vary door to door, an adjustable strike such as the Kwikset 80318 full round adjustable strike absorbs that variation instead, at the cost of the finish range.

They are not the same part. The Emtek 83224 is a deadbolt strike plate - a plain plate for the jamb, matched to a tubular deadbolt. The Kwikset 81825 is a six way adjustable deadlatch, an adjustable component ordered when the bolt and the jamb hole need to be brought into line. Order the 83224 when the plate is what is worn, painted over, or the wrong finish; order the 81825 when the alignment is the problem.

The strike plate is not a keyed part. The Schlage C keyway noted with the 83224 refers to the deadbolt family it is specified alongside, so if you are keying a new Emtek deadbolt into an existing Schlage C system that lines up. The plate itself is just the jamb-side hardware.

The description calls the 83224 brass and the spec attributes list the substrate as steel, so treat the finish as the thing you match on and order to the finish code (US3, US10B, US15, and so on) rather than to the base metal.
