Kwikset 83277 Square Corner Gatelatch Latchbolt, 2-3/8" Backset

The Kwikset 83277 is a 2-3/8 inch backset latchbolt, which is the shorter of the two standard residential and light commercial backsets (the other being 2-3/4 inch). If the cross-bore on your gate or door is centered 2-3/4 inches from the edge, this latch will not reach the spindle correctly and you need a 2-3/4 inch unit instead, such as the Deltana G1RLE275 entry latch or the Schlage 16-228, which is adjustable to either 2-3/8 or 2-3/4 inches.

Square corner. The 83277 latchbolt is made for a door or gate edge that has been routed with a square corner mortise, so it drops into a prep left by another square-corner face plate without re-routing. A round-corner prep needs a round-corner latch instead, like the Schlage 12-289 with its 1/4 inch round corner face.

Just the latch. The 83277 is a replacement latchbolt assembly, so it covers the latch case and face plate only. You keep your existing gate lockset trim, spindle, and strike, or order those separately. Buy this when the latch has seized or the face plate is damaged and the outside hardware is still good.

The Kwikset 83277 is a gate latch latchbolt specified for commercial use, intended as a replacement latch for gate hardware rather than a graded entry latch. If your spec calls out a grade, the Deltana G1RLE238 is a Grade 1 regular latch in entry function at 2-3/8 inch backset, and the Deltana G1RLP238 is the Grade 1 version in passage/privacy at the same backset. The Dexter deadlatch for C1000 series is a Grade 2 option.

The Kwikset 83277 latchbolt has a square corner face at a 2-3/8 inch backset. Two Schlage parts share that corner style: the 12-630 deadbolt latch for B600, B700 and B800 series is a 2-3/8 inch backset with a 1-1/8 by 2-1/4 inch square corner face, and the 16-480 deadlatch for S200 series is adjustable to 2-3/8 or 2-3/4 inch with a 1 by 2-1/4 inch square corner face. Match the face dimension to the mortise already cut in the door edge, since 1 inch and 1-1/8 inch faces are not interchangeable without filling or recutting.

It is a gate latch latchbolt, the spring-actuated latch that retracts when the handle or thumb piece is operated. It is not a deadbolt. If you need a deadbolt latch case in a square corner face, the Schlage 12-630 for B600/700/800 Series is a deadbolt unit.

Yes, if you can accept an adjustable part. The Kwikset 83277 is fixed at 2-3/8 inch backset in satin chrome. For fleet stocking, the Schlage 16-228 for S200 and CS210 series and the Schlage 16-480 for S200 series are both adjustable to 2-3/8 or 2-3/4 inch with square corner faces, so one shelf part covers either bore. Deltana splits by backset instead, with the G1RLE238 and G1RLE275 in entry function and the G1RLP238 and G1RLP275 in passage/privacy, all Grade 1.

No. The Schlage 12-289 is a B500 series deadbolt latch with a 1 by 2-1/4 inch face and a 1/4 inch round corner, adjustable to 2-3/8 or 2-3/4 inch backset. The Kwikset 83277 is a square corner gate latch latchbolt at 2-3/8 inch backset. The corner profile is the deciding difference - a round corner part will not seat in a square corner mortise, and the two serve different lock bodies. For a round corner prep, the 12-289 is the one to look at; for square corner, stay with the 83277 or a square corner Schlage such as the 12-630.

The Kwikset 83277 is a square corner gate latch latchbolt at 2-3/8 inch backset - a plain spring latch for gate hardware. A deadlatch adds a secondary plunger that blocks the latchbolt from being carded back when the door is closed. The Schlage 16-480 for S200 series is a deadlatch with an adjustable 2-3/8 or 2-3/4 inch backset and a 1 by 2-1/4 inch square corner face, and the Dexter deadlatch for the C1000 series is a Grade 2 part. Choose the deadlatch style where the latch is exposed to a loidable gap.
