Emtek 8450MB Single Cylinder Deadbolt Medium Bronze

Product Description

The EMTEK 8450MB is a single cylinder deadbolt designed for residential and light commercial door applications. It accepts both a 2-3/8 inch and 2-3/4 inch backset, making it compatible with the most common door prep configurations found in standard construction. The unit is finished in Medium Bronze and is sized for 1-3/4 inch door thickness. At 2.2 pounds, it is a solid, full-function deadbolt intended for installation by finish carpenters, general contractors, or experienced DIYers working on entry door hardware replacement or new construction.

This deadbolt suits standard residential entry doors requiring a traditional single cylinder lockset. The single cylinder format means it is key-operated from the exterior and thumb-turn operated from the interior — the typical configuration for exterior entry doors in residential settings. The Medium Bronze finish is suited to door hardware sets where an oil-rubbed or aged-metal aesthetic is part of the design scheme. Sold individually as a single unit.

Installation Notes

Installation is typically performed by a finish carpenter, locksmith, or qualified DIYer using a hole saw set, chisel, and screwdriver. Verify door thickness and backset measurement before ordering. Ensure the existing door prep matches the required bore diameter for this deadbolt. Follow local building codes regarding exterior door security hardware requirements.
