Emtek 86084 Full Lip Strike Plate, Square Corners

The 86084 strike plate measures 2-1/4 inches high by 1-5/8 inches wide, which is the common residential face size, so it covers a standard strike mortise. What decides the swap is the lip: lip to center is 7/8 inch, so the lip wraps the jamb edge and returns the latch on that dimension. Hold your old plate against those numbers before you pull it. If the existing cutout is taller or wider than 2-1/4 by 1-5/8, you will see bare jamb around the new plate.

Twelve finishes: Polished Brass Lifetime (US3), Unlacquered Brass (US3NL), Satin Brass (US4), French Antique (US7), Oil Rubbed Bronze (US10B), Polished Nickel Lifetime (US14), Satin Nickel (US15), Pewter (US15A), Flat Black (US19), Polished Chrome (US26), Medium Bronze (MB), and Tumbled White Bronze (TWB). Those are the same Emtek finish codes used across their knob and lever sets, so a property manager standardizing a building can order the strike in the code already on the doors. Order by the code, not the description, since several bronzes read similarly in a photo.

The Emtek 86084 is a fixed full lip strike with square corners and a 7/8 inch lip-to-center dimension, so the lip projection is set and the frame prep has to match it. Where the existing mortise is off, the Kwikset 80318 is a full round adjustable strike and the Kwikset 81825 is a six way adjustable deadlatch, both of which give you movement to meet an opening that was not cut to the plate. The tradeoff is appearance: the 86084 is solid brass and comes in finishes such as Oil Rubbed Bronze (US10B), Satin Nickel (US15), and Polished Brass - Lifetime (US3), so it is the choice when the strike has to match visible hardware on the door.

They serve different latches. The Emtek 86084 is a full lip strike with square corners for a latchbolt, measuring 2-1/4 inches high by 1-5/8 inches wide with a 7/8 inch lip-to-center projection, in solid brass. The Deltana SP2753 is a deadbolt strike plate, 2-3/4 inches by 1-1/4 inches, in steel. If you are prepping a bore for a knob or lever latch, the 86084 is the strike that catches it; if the bore above it takes a deadbolt, the SP2753 is the flat plate for that hole. A door with both typically needs one of each.

The Emtek 86084 is a residential full lip strike, 2-1/4 inches high by 1-5/8 inches wide with square corners, sized for a standard residential jamb cutout. A commercial frame prepped for an ASA strike takes a larger plate: the Codelocks ASA strike plate in stainless steel is the one cut for that prep. Match the plate to the prep already in the frame rather than the latch alone, since the two cutouts are not the same footprint.

A full lip strike has a formed lip that projects past the jamb face and curves toward the door stop, so the latchbolt rides up the lip and into the opening as the door closes. The Emtek 86084 carries a 7/8 inch lip to center dimension, which is what sets how far that lip stands off the jamb. Use one where the latch needs a ramp to seat, typically a spring latch on a knob or lever set. A flat strike with no lip is for a deadbolt, which is thrown by hand and never needs the ramp.

No. The 86084 full lip strike ships with its mounting hardware, so you are not sourcing screws to hang it. If you are anchoring into a hollow jamb or want longer screws driven into the framing behind the jamb for security, that is a separate buy, since the included screws are strike plate length.

It is classified residential. For apartments, single family, and light interior openings it is the right part. For a commercial opening in an office, school, or healthcare corridor, you want a strike carried under a commercial line rather than this one, because the residential designation is what governs how it is specified.

Handing is not a factor for the strike plate itself, since the plate mounts in the jamb and the lip returns toward the stop on whichever side the door closes against. What does matter is which jamb face the mortise is in, and that follows the door's swing. Confirm the existing pocket is 2-1/4 by 1-5/8 inches with square corners and the plate drops in regardless of hand.

It matters for the frame prep. The Emtek 86084 has square corners, so it seats in a mortise routed with square ends; a plate with radius corners is cut for a router-made pocket with rounded ends. Dropping a square corner plate into a rounded mortise leaves gaps at the corners, and a radius plate in a square pocket leaves the corners open. Confirm the corner shape of the existing cutout before ordering, or plan to chisel the mortise to match.

No, those are not substitutes for each other. The Kwikset 81640 is a strike box and the Kwikset 81231-001 is a metal strike dust box, both deadbolt strike components that sit inside the frame mortise to line the bolt pocket. The Emtek 86084 is the visible strike plate itself, 2-1/4 inches by 1-5/8 inches with a full lip and square corners, that screws to the face of the jamb and catches the latch. A dust box goes behind a plate, not instead of one.

The catalog spec lists the substrate as steel, while the product features call it solid brass construction. Practically, the finish codes are Emtek's standard plated finishes, so what you see on the door is the plated face. If the base metal decides your order, specify it on the purchase order.

It is sold as a replacement part on its own. That is how you order a single strike when one plate on a building is damaged, stripped, or wrong finish, without buying a whole knob or lever set to get it. Buying a dozen in one finish code to bring a set of doors back to matching is the normal use.
