Kwikset 83000 - 6AL Adjustable Square Drive Latch

Function is the choice you make when ordering the Kwikset 83000 latch, and it changes how the door secures. The deadlatch version has the small auxiliary plunger alongside the main latchbolt, so once the door is closed the bolt cannot be shimmed or carded back. That is what you want on any exterior or entry opening, and on keyed knobs and levers generally. The plain latch has no deadlocking plunger and just springs into the strike, which is what belongs on a passage or privacy door where nothing is being secured. Both functions are offered in all five finishes.

All three. The 83000 ships with three interchangeable faceplates: round corner, square corner, and a drive-in collar. So whether the existing prep in the door edge is a routed square mortise, a radius-corner mortise from a router jig, or a bare bored hole with no mortise at all, you swap to the matching faceplate rather than reworking the door. That is the main reason this latch gets specified on retrofit work where the door edges are not consistent from opening to opening.

Adjustable means the latch covers both common residential backsets in one part, so you do not need to measure the door before ordering. You set it on site to match the distance from the door edge to the center of the bore. 2-3/8 inch and 2-3/4 inch are the two standard backsets, and an adjustable latch is the usual way property managers and maintenance crews carry one part number across a building instead of stocking two.

Treat the 83000 as a Kwikset replacement part. It is the square drive latch Kwikset builds for its own cylindrical knobs and levers, and the drive tailpiece and chassis engagement are what tie it to that hardware. Cross-brand latch swaps between cylindrical lines are not something to assume: the bore and cross bore may be standard, but the retractor engagement often is not. If the lock body on the door is a Kwikset, this is the correct latch to replace.

Usually not. On a cylindrical knob or lever, the latch is a separate part from the lock body, and a worn or bent latch is the most common failure on a high traffic apartment or office door. The Kwikset 83000 replaces just that piece: pull the two faceplate screws and the old unit slides out of the door edge. You keep the existing knob or lever, the keying stays as it is, and the door edge prep does not change because the 83000 carries square corner, round corner, and drive-in faceplates in the box.

Five finishes: 11P Venetian Bronze, 15 (also called 619) Satin Nickel, 26 or 625 Polished Chrome, 26D or 626 Satin Chrome, and 514 or 622 Matte Black. Those are Kwikset's own finish codes with the BHMA equivalents alongside, so matching an existing lockset is a matter of reading the code off the packaging or the back of the rose. Only the faceplate shows once the latch is installed, so the finish choice is about the door edge, not the trim.

Not handed. A cylindrical latch of this kind is reversible, so the same 83000 serves a left hand or right hand opening, inswing or outswing. If the bolt is facing the wrong way when you pull it out of the box, you rotate the latchbolt to face the stop rather than ordering a different part. For anyone buying in quantity for a mixed building, that means one SKU per finish and function covers every door.

No. Different systems entirely. The 83000 is a Kwikset cylindrical latch for bored knob and lever prep. For an ML2000 mortise lock the parts are model specific: Corbin Russwin makes the 429F31 screw packet for the N escutcheon, the 433F77 screw pack for the M and P escutcheons, the 206F57-8 strike combo screw, and the 425F86-8 flat screw in 8-32 x 3/8 inch. Match the escutcheon style on the door to pick between them.

For a labeled fire door, specify a latch that carries the listing on its own paperwork. The 83000 is Kwikset's residential-grade cylindrical latch for bored knob and lever prep, and fire openings in commercial buildings generally take Grade 1 or Grade 2 hardware with the label documentation to match. On the unrated interior and residential doors in the same building it is the correct part.

What the 83000 covers is the latch unit itself with its three interchangeable faceplates: round corner, square corner, and drive-in collar. If the frame side is also damaged, order the strike separately. On a straight latch swap in an existing opening the strike is normally reused, since the latch is set to the same backset and the strike position in the jamb does not move.
