Deltana 178AST Angle Strike, 1-7/8" x 1-1/8", Solid Brass

1-7/8 x 1-1/8 inches is the plate footprint. That's a small plate, so it lands on most door stops and jamb faces without overhang, but measure the flat face you're mounting to: you need 1-7/8 inches of run in one direction and 1-1/8 in the other. On a narrow aluminum stop or a tight rabbet, check that before you drill.

The Deltana 178AST is an angle strike sized 1-7/8 inch by 1-1/8 inch for use with surface bolts, so it is prepped for a bolt that rides on the face of the door, not one that throws from inside the door edge. For a deadbolt, the Emtek 83223 is a standard deadbolt strike plate with square corners, and the Kwikset 80318 is a full round adjustable strike. Both are deadbolt strike plates rather than surface bolt strikes, so pick by the bolt already in the door before you pick the finish.

Deltana rates the 178AST for commercial use. It's solid brass rather than plated steel or zinc, which is what keeps it serviceable on an exterior or high-traffic opening where a thin stamped plate would deform around the bolt pocket. Property managers standardizing surface bolt hardware across a building can run the same strike on every opening and just vary the finish.

The Deltana 178AST is a fixed solid brass angle strike at 1-7/8 inch by 1-1/8 inch, so alignment is handled by how you lay out and mortise it. Where the bolt lands off center and you want the strike itself to take up the error, the Kwikset 80318 is a full round adjustable strike and the Kwikset 81825 is a 6 way adjustable deadlatch. Both are deadbolt strike parts, so they suit a bored deadbolt opening rather than a surface bolt.

The Deltana 178AST is solid brass and comes in PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome and Paint Black, which is what lets it follow existing decorative trim across a run of doors. The Codelocks ASA strike plate is offered in a stainless steel finish and is part of the ASA strike plate series, a single appearance intended to sit with the lock it serves. Match the strike to whichever the rest of the opening is already keyed to visually.

Each. The unit of measure is a single strike, so a pair of doors with a bolt top and bottom on the inactive leaf takes two 178ASTs, and you order two.

The Codelocks ASA strike plate is the strike that belongs to the Codelocks ASA strike plate series, so it is the one to order when the opening carries that lock. The Deltana 178AST is a different job entirely: an angle strike, 1-7/8 inch by 1-1/8 inch in solid brass, for use with surface bolts on the head or sill of a door such as an inactive leaf on a pair. A door can carry both, one strike for the latch and one for the surface bolt.
