Deltana SPDB478 ANSI Blank T-Strike, 4-7/8" x 1-1/4", with Hole, Solid Brass

Blank means the SPDB478 ships without the latch opening cut through the face, apart from the single hole it comes with. It is used where the opening gets cut or matched to the specific latch and lip projection you need, or as a filler over an existing 4-7/8 inch ANSI prep. If you want a ready-cut strike for a standard cylindrical latch, buy a finished ANSI strike instead of the blank.

They serve different parts of the opening. The SPDB478 is an ANSI T-strike measuring 4-7/8 inches by 1-1/4 inches in solid brass, the tall plate that mortises into the jamb opposite a commercial lockset. The Emtek 83223 is a standard deadbolt strike plate with square corners, sized for the deadbolt bore alone. If the door carries a separate deadbolt above a knob or lever, the deadbolt strike is a second plate, not a replacement for the T-strike.

Yes. The Deltana SPDB478 is a fixed ANSI T-strike with a single hole location, so the jamb prep has to match it. Where the bolt no longer meets the strike, the Kwikset 80318 full round adjustable strike and the Kwikset 81825 6 way adjustable deadlatch are both deadbolt strike plates built to take up that misalignment without recutting the mortise. Both are Kwikset residential-pattern parts rather than the ANSI commercial plate, so confirm the existing jamb cutout before swapping.

No, and they are commonly ordered together by mistake. The Deltana SPDB478 is the visible face plate, 4-7/8 inches by 1-1/4 inches of solid brass, that screws to the jamb. The Kwikset 81640 strike box and the Kwikset 81231-001 metal strike dust box are the cup that sits behind the plate inside the jamb pocket to line the bolt cavity. A buyer replacing a damaged face plate wants the strike plate; a buyer whose jamb pocket is chewed out wants the box.

The Codelocks ASA strike plate is the closest match in intent: ASA is the same industry strike pattern the Deltana SPDB478 is cut to, and it comes in a stainless steel finish rather than brass. The Deltana SPDB478 is the solid brass version of that plate at 4-7/8 inches by 1-1/4 inches, offered in polished brass, PVD polished brass, antique brass, oil rubbed bronze, brushed nickel, antique nickel, polished chrome, and brushed chrome. Facilities that want a single non-plated look on every jamb usually run stainless; facilities matching existing brass lever trim run the Deltana.

Commercial. The SPDB478 is an ANSI strike made for commercial locks, and it is solid brass rather than stamped steel, so it holds up on openings that see constant use. Property managers standardizing a building can run the same strike across every commercial opening cut to the 4-7/8 inch ANSI prep.

Eight finishes: polished brass, PVD polished brass, antique brass, oil rubbed bronze, brushed nickel, antique nickel, polished chrome, and brushed chrome. The PVD polished brass is the one to pick if you want the brass look to hold on an exterior opening, since PVD is a plated coating over the brass rather than a lacquer. All eight are on the same solid brass plate, so the strike matches the rest of a Deltana-finished opening.

The SPDB478 is the face plate only, no dust box included. On a hollow metal frame the frame cavity behind the ANSI prep usually serves that purpose. On a wood jamb you want a box behind the latch opening so the bolt is not throwing into raw framing, and ZenSupply carries the Kwikset 81640 strike box and the Kwikset 81231-001 metal strike dust box for that.

They are the same 4-7/8 inch commercial standard, just two names for it, ASA being the older designation. The choice is really material and finish: the Deltana SPDB478 is solid brass in eight architectural finishes, while the Codelocks ASA strike plate is a stainless steel finish plate sold for Codelocks hardware. Pick the brass when the strike has to match brass or bronze trim on the opening.

The deadbolt needs its own plate. The Deltana SPDB478 ANSI T-strike, 4-7/8 inches by 1-1/4 inches, covers the latch position for the lockset. For the separate deadbolt bore, the Emtek 83223 standard deadbolt strike plate with square corners suits a squared jamb cutout, while the Kwikset 80318 full round adjustable strike suits a rounded router cut and allows alignment adjustment. Match the plate corner shape to how the jamb was routed.

It is not an equivalent swap. The Deltana SPDB478 is an ANSI T-strike specified for commercial locks, 4-7/8 inches by 1-1/4 inches in solid brass. The Kwikset 80318 full round adjustable strike and Kwikset 81825 6 way adjustable deadlatch are deadbolt strike plates on the residential bore pattern, so they neither fill nor cover the tall ANSI mortise a commercial jamb is prepped for. On an opening already cut for ANSI strike prep, the T-strike is the part that fits.

Yes, the SPDB478 is sold each, so you can buy a single plate for one opening or count out exactly what a floor needs. Useful on retrofit work where only a handful of frames are getting a new strike.

Solid brass through the plate, not brass plating over steel, so wear at the lip does not expose a different metal underneath and it will not rust. For a coastal or heavy weather opening, the PVD polished brass version is the more durable finish choice among the eight offered.
