Emtek LC4-DLB275R-US15 Deadlatch 2-3/4 in Backset Satin Nickel

Product Description

The EMTEK LC4-DLB275R-US15 is a key-in lever or knob deadlatch designed for residential and light commercial door hardware applications. This deadlatch features a 2-3/4 inch backset and a 1/4 inch radius corner faceplate, finished in Satin Nickel (US15). A deadlatch provides spring-loaded latch bolt action with an anti-pick deadlocking plunger, securing the latch against forced retraction when the door is closed. It is installed by locksmiths, carpenters, and general contractors as part of a complete door hardware assembly.

This deadlatch is intended for use with key-in lever or knob locksets that require a 2-3/4 inch backset, a standard measurement common in residential entry doors and interior privacy applications. The 1/4 inch radius corner faceplate suits door prep cutouts machined to that specification. The Satin Nickel finish integrates with a wide range of door hardware finishes and trim styles. It is sold individually and is compatible with standard EMTEK lever and knob chassis assemblies.

Installation Notes

Installation is performed by a licensed locksmith, finish carpenter, or qualified contractor. Before servicing or replacing a deadlatch, ensure the door is open and no load is applied to the latch mechanism. Standard door prep tools including a hole saw, chisel, and faceplate mortise router are typically required. Verify the door backset measurement and corner radius of the existing faceplate cutout before ordering to confirm fitment.
