Kwikset 83518-003 Adjustable Radius Corner Deadlatch

Product Description

The KWIKSET 83518-003 is a UL-listed adjustable radius corner deadlatch designed for residential door installations. The latch features a radius corner faceplate that adjusts to fit both standard square-corner and radius-corner door prep cutouts, reducing the need for chiseling or additional mortising. Finished in satin nickel, it suits a range of interior and exterior door hardware configurations. At 3.7 inches in length, 2 inches in width, and 0.9 inches in height, the unit ships as a single piece and weighs 0.3 pounds. Licensed locksmiths, carpenters, and general contractors install this latch as part of a complete door hardware assembly.

This deadlatch is suited for residential applications where a dependable spring latch with deadlocking plunger action is required. The adjustable radius corner faceplate makes it compatible with doors prepped for either square or radius corner strike cutouts, which is common in tract housing and retrofit installations. It works with standard tubular lockset bore configurations and is appropriate for both new construction and replacement projects in single-family and multi-family residential settings.
