Schlage Lock Co 40-251 605 Triple Option Deadlatch 4 Pack

Product Description

The SCHLAGE LOCK CO 40-251 605 TRIPLE OPTION is a triple option deadlatch designed for residential and light commercial entry door applications. It ships in a visual pack of four units and accepts both 2-3/8 inch and 2-3/4 inch backset configurations, giving installers flexibility across a range of door preparations. The latch is compatible with square corner, radius corner, and drive-in installation methods, eliminating the need to stock multiple latch styles for different door preps. Licensed locksmiths, carpenters, and general contractors routinely specify this latch for new construction and retrofit work.

This deadlatch is intended for use with Schlage F Series entry locksets, making it a common replacement or supplemental component in residential entry door hardware projects. Its multi-option design suits standard hollow-core and solid-core door preparations found in single-family homes, apartments, and light commercial suites. The drive-in option is particularly useful when a faceplate mortise has not been cut, speeding up installation on pre-hung door slabs.
