Deltana SPBDB478 ANSI Blank T-Strike, 4-7/8" x 1-1/4", Without Hole, Solid Brass

Yes. The SPBDB478 is an ANSI blank T-strike measuring 4-7/8 x 1-1/4 inches, which is the standard ANSI strike cutout size used on commercial hollow metal frames. If your frame is already prepped for a 4-7/8 inch ANSI strike, this drops straight into that mortise. Frames prepped for a small 2-3/4 inch T-strike or a residential 1-1/8 x 2-3/4 inch plate will not take it without recutting the frame.

It ships blank, meaning the face has no lip cutout machined for the latchbolt. You cut the opening yourself to match the lock you are installing. That is the point of a blank: one plate covers whatever latch and deadbolt configuration is in the door instead of forcing you to source a strike machined for that exact lock. If you want a plate that arrives ready to use with no fabrication, order a pre-cut strike instead.

If the opening was prepped to the 4-7/8 inch ANSI standard, yes: the plate is 4-7/8 x 1-1/4 inches and lands on the same footprint, and because it comes blank you can cut the latch opening to match whatever lock is in the door rather than hunting a strike machined for that specific lockset. If the old strike is a smaller T-strike, the ANSI plate is larger than the existing cutout, so you are enlarging the frame mortise rather than covering it.

The Codelocks ASA Strike Plate is the closest counterpart when the opening calls for an ANSI/ASA-format faceplate in a stainless steel finish rather than brass. The Deltana SPBDB478 is a solid brass ANSI blank T-strike measuring 4-7/8 inches by 1-1/4 inches, supplied without a hole so the lip and latch opening can be cut to suit the lock and frame. The Codelocks part covers the same ASA strike-plate role; the Deltana is the choice when the strike has to match brass trim already on the opening, since it comes in Polished Brass, Antique Brass, PVD Polished Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome and Brushed Chrome.

Use a deadbolt strike plate such as the Emtek 83223 Standard Deadbolt Strike Plate with square corners, or the Kwikset 80318 Full Round Adjustable Strike where a round-corner prep is already cut in the jamb. The Deltana SPBDB478 is a commercial ANSI blank T-strike in the 4-7/8 inch by 1-1/4 inch ANSI format, sized for the tall ANSI jamb prep that commercial locksets use. A standard deadbolt prep is much shorter, so the Emtek and Kwikset deadbolt strikes drop into that prep directly while the ANSI plate would require reworking the frame.

Solid brass, not plated steel. Material and substrate are both brass, which matters two ways: it machines cleanly when you cut the latch opening, and it will not rust-bleed on an exterior opening the way a plated steel plate does once the coating is nicked. Brass is also softer than stainless, so on a high-abuse opening it can deform under repeated strike impact.

Eight finishes: Polished Brass, PVD Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, and Brushed Chrome. If you are standardizing a building, the PVD Polished Brass holds its color better than standard polished brass on exterior and high-touch openings, since PVD is a hard vacuum-deposited coating rather than a lacquer.

The SPBDB478 is a commercial-rated part built to the ANSI strike format for commercial locks. It will physically work on a residential door only if that door's frame is prepped for a full 4-7/8 inch ANSI cutout, which is uncommon on residential construction. For a typical house door, a deadbolt strike plate such as the Emtek 83223 with square corners or the Kwikset 80318 full round adjustable strike is the right size class.

No dust box is included; the SPBDB478 is the face plate only. On a hollow metal frame with an existing ANSI strike pocket you usually already have the box formed into the frame. On wood jambs or where the pocket is open, add a separate box so the bolt lands in a closed cavity rather than bare framing. The Kwikset 81231-001 metal strike dust box and the Kwikset 81640 strike box are both stocked for that.

Different jobs. A blank plate like the Deltana SPBDB478 is for commercial ANSI-prepped frames where you cut the lip opening to suit the lock and want a specific finish across a building. An adjustable strike, such as the Kwikset 81825 six-way adjustable deadlatch, is for correcting alignment on a door that has settled or a frame that is out of position. If your problem is the door not latching cleanly, adjustable solves it; if your problem is a damaged or mismatched plate on an ANSI prep, the blank does.

ASA and ANSI describe the same 4-7/8 x 1-1/4 inch commercial strike format, so the SPBDB478 fits an ASA-prepped frame. The difference from something like the Codelocks ASA strike plate in stainless steel is finish and material: the Deltana is solid brass in eight decorative finishes and blank, so you cut the opening; the Codelocks plate is stainless. Choose on finish match and whether you want a pre-cut plate.

No. The Kwikset 81640 is a strike box and the Kwikset 81231-001 is a metal strike dust box - both are the cup that sits behind the faceplate inside the jamb mortise, catching the bolt and keeping debris out of the pocket. The Deltana SPBDB478 is the faceplate itself: a solid brass ANSI blank T-strike, 4-7/8 inches by 1-1/4 inches, supplied without a hole. On an ANSI opening the two are used together, not in place of each other, so ordering a strike box does not give you a surface plate for the jamb.

Where the door and frame are out of alignment, an adjustable strike is the better answer: the Kwikset 80318 Full Round Adjustable Strike or the Kwikset 81825 6 Way Adjustable Deadlatch both allow the catch point to be shifted after mounting. The Deltana SPBDB478 is a fixed ANSI blank T-strike in solid brass, 4-7/8 inches by 1-1/4 inches, supplied without a hole - the latch opening is cut to suit, which makes it the choice on a correctly prepped ANSI commercial frame where the plate position is set by the existing mortise rather than adjusted in the field.

The Deltana SPBDB478 is the ANSI-format option: a solid brass ANSI blank T-strike, 4-7/8 inches by 1-1/4 inches, rated for commercial use and offered in eight finishes including Polished Chrome, Brushed Chrome, Brushed Nickel and Antique Nickel, which lets one part number carry across openings with different trim finishes. The Codelocks ASA Strike Plate is the same ASA format in a stainless steel finish, a single-finish choice where appearance is uniform throughout. The Emtek 83223 is a standard deadbolt strike plate with square corners, sized for deadbolt preps rather than the ANSI mortise, so it covers a different set of doors in the same building.

Sold individually, each, with the price shown per unit, so quantity is just the number of openings you are doing. Model number is SPBDB478 and the only choice on the order is finish. If you are standardizing a facility, pick one finish and one part number and it repeats across every ANSI-prepped opening.
