Kwikset 83518 - RCAL Adjustable Square Drive UL 3 hour Latch

The 83518 is the latch that goes into the door edge bore for a Kwikset deadbolt, with an adjustable square drive tailpiece. It is a residential deadbolt part, not a lever or knob latch, and it is not the strike that mortises into the jamb.

Both. The 83518 is an adjustable latch, so the same part covers the two backsets used on residential doors, 2-3/8 inch and 2-3/4 inch. You set it at install rather than ordering a backset-specific latch.

That is what it is for. If the cylinder and thumbturn are fine and only the bolt assembly failed or the backset is wrong for the door, the 83518 drops in as the replacement latch and keeps the existing Kwikset deadbolt trim. Match the finish so the exposed edge plate blends: it comes in Satin Nickel and Venetian Bronze.

It carries a UL 3 hour rating, which is what lets it be used in a rated opening where the deadbolt assembly is part of the fire door assembly. Note that it is a residential-classified part, so confirm the whole assembly matches the rating your opening was listed under.

Square drive refers to the shape of the tailpiece slot the deadbolt cylinder turns. The 83518 uses a square drive, so it mates to Kwikset deadbolt cylinders built for that drive. A round-drive or blade-drive deadbolt will not turn it, so pull your old latch and look at the drive shape before ordering.

The Kwikset 83518 is a mechanical deadbolt latch with an adjustable square drive, so it serves a keyed or thumbturn deadbolt driven by hand. If the opening is being fitted with an electrified deadbolt instead, the Emtek LC9-DBLTCH EMPowered motorized deadbolt latch is the deadbolt-function part in the set, listed as a motorized deadbolt latch rather than a hand-driven one. Both sit in a deadbolt bore, but the EMPowered latch is built to be thrown by the motorized lock body it belongs to, so it is a substitution only when the whole deadbolt is changing over.

No. The Deltana DLE23875 is an adjustable drive-in latch with an entry function, meaning it works with a keyed knob or lever that retracts a spring latch. The Kwikset 83518 is a deadbolt latch with an adjustable square drive, which throws a solid bolt from a thumbturn or key cylinder and does not retract when the door is pushed. They serve the two separate bores in a typical entry door, so a DLE23875 belongs in the knob or lever bore and the 83518 in the deadbolt bore above it.

The 83518 is a mechanical latch with no electrification. If the goal is a powered deadbolt, the Emtek LC9-DBLTCH EMPowered motorized deadbolt latch is the powered deadbolt latch we carry. That is a different assembly, not a swap into a Kwikset deadbolt.

It is classified as a residential product, so it suits apartments, single-family rentals and light multi-family openings rather than a commercial-grade standardization program. A property manager replacing failed deadbolt latches across a portfolio of Kwikset-equipped units can buy it in quantity in either Satin Nickel or Venetian Bronze to match what is already hung.

Use a passage or privacy latch rather than a deadbolt latch. The Deltana DLP23875 is a drive-in latch with an adjustable backset of 2-3/8 inch or 2-3/4 inch in a passage/privacy function, and it fits doors 1-3/8 inch to 2 inch thick. The Kwikset 83518 is a deadbolt latch, so it has no function on a door that only needs to stay closed or hold a bathroom or bedroom privacy turn.

No, despite the similar number. The Emtek 83228 is a faceplate and screws for a tubular pocket door privacy latch with square corners, a trim part for a sliding pocket door in a privacy/bed/bath function. The Kwikset 83518 is a deadbolt latch with an adjustable square drive for a swinging door. The two do not share an application, and the Emtek part does not include a latch body.

Two: Satin Nickel and Venetian Bronze. Pick the one that matches the deadbolt already on the door, since the latch face shows on the door edge when the door is open.

The Kwikset 83518 adjustable square drive deadbolt latch is offered in Satin Nickel and Venetian Bronze, which lets the exposed faceplate match the deadbolt trim on the door edge. Among the other deadbolt-function parts, the Emtek LC9-DBLTCH EMPowered motorized deadbolt latch is specified by its EMPowered series rather than by a matching finish range, so finish matching across a set of doors is straightforward with the 83518.
