Emtek 86148 Brass Flat Strike Plate with understrike and screws

The 86148 measures 1-7/8 inches wide by 4-7/8 inches high. Measure the plate currently in your jamb: anything smaller than that footprint will be covered, anything larger leaves exposed routing you would need to fill or a new strike prep. That tall, narrow footprint is the standard mortise-lock strike shape, not the short 2-3/4 inch plate used on deadbolts and cylindrical latches.

They cover different openings. The Emtek 86148 is a brass flat strike plate measuring 1-7/8 inches wide by 4-7/8 inches high, sized as a replacement part for F20 and F13 mortise entrance locksets, and it ships with an understrike and screws. The Deltana SP2753 is a deadbolt strike plate in steel at 2-3/4 inches by 1-1/4 inches. The 86148 is the tall mortise-length plate that catches a mortise lock's latch and deadbolt together; the SP2753 is the short square plate that serves a separate tubular deadbolt bore. If the door has a mortise lock body, the short deadbolt plate will not cover the prep.

An alignment problem is not a plate problem. The Emtek 86148 is a fixed brass flat strike plate at 1-7/8 inches by 4-7/8 inches, made as the replacement plate for F20 and F13 mortise entrance locksets - it goes back into the same mortar of prep the original came out of and does not move the catch point. Kwikset offers adjustable strike hardware for the misalignment case: the KWI-80318 full round adjustable strike and the KWI-81825 6 way adjustable deadlatch, both deadbolt strike hardware. Order the 86148 when the existing prep is right and the plate is damaged or the finish is wrong; reach for the adjustable Kwikset hardware when the bolt is hitting off center.

Both are in the box. The 86148 includes the understrike (the box or underplate that sits behind the face plate in the jamb mortise) and the screws to mount it, so a single order finishes the jamb side. You are not sourcing a separate dust box the way you would with some deadbolt strikes.

It is a flat, fixed-face strike, so alignment comes from the jamb prep rather than from the plate. If your door has settled and the latch is missing the strike opening, a fixed brass plate will not take up that error. Adjustable options exist in other lines for that problem, such as the Kwikset 80318 full round adjustable strike or the Kwikset 81825 six-way adjustable deadlatch, though neither is an Emtek mortise-lock match.

If they are all F20 or F13 mortise entrance locksets, yes, the 86148 is the common flat strike across them, and you can hold one finish across the whole run. Order the count you need in a single finish and the jambs will read the same from door to door. Openings running a different Emtek lock family, or a tubular latch, take a different strike.

Not for a finish-matched entry. The Codelocks ASA strike plate is supplied in a stainless steel finish only, so it reads as a single utility color. The Emtek 86148 is a brass flat strike plate offered in Oil Rubbed Bronze (US10B), Medium Bronze (MB), French Antique (US7), Tumbled White Bronze (TWB), Satin Nickel (US15), Pewter (US15A), Flat Black (US19), Polished Chrome (US26), Polished Brass - Lifetime (US3), Satin Brass (US4), and Unlacquered Brass (US3NL). On a visible residential entry where the plate sits next to the lockset, the brass plate in a matching bronze finish is the one that disappears into the door; the stainless ASA plate is the choice where appearance is not the deciding factor.

The Emtek 86148 ships with an understrike and screws, which is the plate assembly for the mortise prep it replaces. The Kwikset 81640 strike box and the Kwikset 81231-001 metal strike dust box are separate deadbolt strike components - they are the cup that lines the bolt pocket in the jamb, sold on their own rather than as part of a face plate. They are not accessories to the 86148 and are not a substitute for it; a buyer holding a Kwikset deadbolt jamb prep orders those, a buyer replacing the face plate on an F20 or F13 mortise entrance lockset orders the 86148.

Emtek classifies the 86148 as residential door hardware. Property managers standardizing across apartments, condos, and single-family units are the right fit. For a commercial opening under a hardware schedule that calls for a graded strike, spec the strike that comes with the graded lock instead.

No wiring involved. It is a mechanical brass strike plate with an understrike and screws, not an electric strike, so there is nothing to connect to an access control panel and nothing that fails when the power drops. If you need release from a card reader or intercom, an electric strike is a different part entirely.

They suit different door populations. The Emtek 86148 is a residential brass flat strike plate carried in eleven finishes, sized 1-7/8 by 4-7/8 inches for F20 and F13 mortise entrance locksets - the fit for unit entry doors that already carry Emtek mortise hardware and need to match across the floor. The Codelocks ASA strike plate is an ASA-series strike in stainless steel, the standard back-of-house profile that pairs with code-entry hardware on service and common-area doors. A property standardizing a building often ends up with both: the brass plate on the resident-facing openings and the ASA plate where the hardware is keypad driven.
