Emtek LC4-DLB2375R-US19 Deadlatch 2-3/8in Backset Flat Black

Product Description

The EMTEK LC4-DLB2375R-US19 is a deadlatch designed for use with key-in-lever or key-in-knob locksets. It features a 2-3/8 inches backset and a 1/4 inches radius corner faceplate, making it a standard replacement or new-installation component for residential and light commercial door prep. The flat black (US19) finish provides a consistent aesthetic match for coordinated hardware sets. At 0.2 pounds, this is a compact, single-unit component that drops into a standard door bore without modification when dimensions align. Installers working on pre-hung or existing doors will find the radius corner faceplate suits the most common door edge prep found in residential construction.

This deadlatch is suited for interior and exterior door applications where a key-in-lever or key-in-knob entry set is being installed or serviced. The 2-3/8 inches backset is the standard dimension found on most residential interior and exterior doors, particularly in older construction and many new builds. The flat black finish is appropriate for matching contemporary or transitional hardware schemes. It is typically installed by finish carpenters, locksmiths, or general contractors during new construction, renovation, or hardware replacement work.

Installation Notes

Installation is typically performed by a finish carpenter or licensed locksmith. Before servicing or replacing door hardware, ensure the door is held open or secured to prevent movement during work. Verify backset measurement from the door edge to the center of the bore hole before ordering to confirm fitment. Follow local building codes for egress and accessibility requirements where applicable.
