The EMTEK LC4-DLB2375R-US10B is a key-in lever or knob deadlatch designed for residential and light commercial door hardware applications. It features a 2-3/8 inches backset and a 1/4 inches radius corner faceplate, finished in Oil Rubbed Bronze. The deadlatch is a critical component in door lockset assemblies, providing the spring-loaded bolt action that keeps a door latched when closed. This part is typically installed by locksmiths, finish carpenters, or experienced general contractors during door hardware replacement or new installation work.
This deadlatch suits interior and exterior door applications where a key-in lever or knob lockset is specified. The 2-3/8 inches backset is standard for many residential interior doors, and the 1/4 inches radius corner faceplate fits the corresponding mortise prep. The Oil Rubbed Bronze finish coordinates with matching EMTEK lever, knob, and rosette hardware. It ships as a single unit and is custom assembled to order.
Designed as an OEM-style replacement or new-installation deadlatch for key-in lever or knob door locksets requiring a 2-3/8 inches backset and 1/4 inches radius corner faceplate prep.
Installation is typically performed by a locksmith or skilled finish carpenter. Power tools are not required for a straight swap, but a chisel and drill may be needed if the door prep requires adjustment. Ensure the door is secured open and all existing hardware is removed before beginning. Verify the backset measurement and corner radius of the existing mortise cutout before installing to confirm fitment.
