Deltana SP2751 Strike Plate, Dust Cup, Adjustable, 2-3/4" x 1-1/4", Steel

The SP2751 is the strike side of the opening, not the lock. It combines a 2-3/4 x 1-1/4 inch steel strike plate with a dust cup (the box behind the plate that catches the bolt in the frame) and an adjustable tab so the lip can be tuned to how the door sits. Adjusting that lip is how you take up a door that has settled or a frame that is slightly out, so the latch or bolt seats instead of rubbing or rattling.

That is the case this strike is built for. Because the SP2751 is adjustable, you can shift the strike engagement rather than plane the door or move the hinges. It only works within the mortise you already have: the plate face is 2-3/4 x 1-1/4 inches, so if your existing strike cutout is that size or smaller you are drilling nothing new. A door that has dropped far enough to need a bigger cutout is past what an adjustable strike will recover.

2-3/4 x 1-1/4 inches is the common full-lip strike footprint used on residential and light commercial bored locksets, so on most standard frames the SP2751 drops into the existing mortise. Measure the plate currently in the jamb before ordering: if yours is the taller 4-7/8 inch ANSI strike, this is not a swap, and if yours is a small deadbolt-only strike you will be enlarging the mortise to take the larger plate.

They solve two halves of the same job. The Deltana SP2751 is a complete adjustable dust cup strike for locks, a 2-3/4 inch by 1-1/4 inch steel plate with the dust cup built in, so one part gives you both the visible strike face on the jamb and the pocket the bolt drops into. The Kwikset 81231-001 is a metal strike dust box on its own - it is the recessed box that lines the mortise behind the plate, not a finished strike face. If the jamb already has a plate you are keeping and you only need to line or re-line the bolt pocket, the 81231-001 is the piece; if you are replacing the whole strike, the SP2751 covers plate and cup together.

Both are adjustable strikes, but the jamb prep decides it. The Deltana SP2751 is a rectangular 2-3/4 inch by 1-1/4 inch plate, so it drops into the standard rectangular strike mortise already cut in most jambs. The Kwikset 80318 is a full round adjustable strike, a circular face that needs a bored round prep instead. On a retrofit, match the shape of the cutout that is already there - a round strike in a rectangular mortise leaves the corners of the old cut exposed, and a rectangular plate over a bored hole will not cover it either. Both carry the adjustment that lets you tune bolt engagement after the door settles.

Five finishes: Polished Chrome, Brushed Chrome, Polished Brass, Antique Brass, and Paint Black. That range covers the two chromes for matching brushed or bright nickel-look trim, two brasses for warm hardware, and black for painted or dark bronze-look openings. Property managers standardizing a building normally pick one and order the strike in the same finish as the lockset trim on those doors.

Deltana lists the SP2751 as commercial, and it is steel through the plate and cup rather than a stamped brass facade. Steel is what you want on a strike taking repeated latch impact in a multi-family corridor or an office suite. For an aluminum storefront or a hollow metal frame with an ANSI prep, the footprint is the deciding factor, not the material.

Deltana describes the SP2751 as an adjustable dust cup strike for locks, without restricting it to a bolt type. The practical limit is the hole and the cup depth against your bolt: match the plate opening to the bolt you are receiving before you cut. If your job is specifically a deadbolt strike, the Emtek 83223 Standard Deadbolt Strike Plate with square corners and the Kwikset 80318 Full Round Adjustable Strike are both listed as deadbolt strike plates.

Use the strike that matches the lock's format. The Codelocks ASA strike plate is an ASA-format plate in a stainless steel finish, cut to the ASA standard those locks are prepped for. The Deltana SP2751 is a 2-3/4 inch by 1-1/4 inch adjustable dust cup strike in steel, sized for standard residential and light commercial strike preps rather than the ASA pattern. If the lock and jamb are prepped ASA, the ASA plate is the fit; the SP2751 covers the standard rectangular prep and comes in Paint Black, Polished Chrome, Brushed Chrome, Polished Brass and Antique Brass to match surrounding trim.

Look at which bolt is missing. The Deltana SP2751 is an adjustable dust cup strike, so it gives you adjustment at a single strike location - enough to recover a deadbolt or latch that has drifted slightly as the door settled. For an opening that has moved further, the Kwikset 81825 is a 6 way adjustable deadlatch, which takes up misalignment in more directions than a single-plane adjustment can. The 81825 is a deadlatch, so it is the latch mechanism rather than the jamb-side plate; the SP2751 stays the jamb-side answer when the door hardware itself is staying put.

The Emtek 83223 is a standard deadbolt strike plate with square corners - a fixed strike face with no adjustment built in, for an opening where the jamb prep and bolt already line up and nothing needs tuning. The Deltana SP2751 is the adjustable version, a steel dust cup strike at 2-3/4 inch by 1-1/4 inch, and the adjustment earns its keep on doors that have settled or on a jamb you expect to move. Square corners on the 83223 also matter for prep: a square-corner plate suits a chiseled square mortise, where a radius-corner plate suits a routed one.

Only if a box is what the job needs. The Kwikset 81640 is a strike box - the recessed liner that sits inside the jamb mortise behind the plate. The Deltana SP2751 is a finished adjustable dust cup strike, steel, 2-3/4 inch by 1-1/4 inch, with a visible face that goes on the jamb in one of five finishes including Polished Chrome and Polished Brass. A strike box has no finished exposed face, so ordering the 81640 for a jamb that needs a new visible strike leaves the opening incomplete. Order the 81640 when you are reinforcing or lining the pocket behind an existing plate.

Each. The Deltana SP2751 dust cup strike is sold as a single unit, so a contractor doing eight doors orders eight. Worth knowing on a re-key or a turn where you only need the one jamb corrected.
