Emtek 8450US3 Single Cylinder Deadbolt Polished Brass

Product Description

The EMTEK 8450US3 is a single cylinder deadbolt designed for residential and light commercial entry doors. It supports both a 2-3/8 inch and 2-3/4 inch backset, making it compatible with standard door preparations across a wide range of door styles. The Polished Brass Lifetime finish (US3) provides a bright, durable surface treatment suited for exterior and interior applications. Designed for 1-3/4 inch thick doors, this deadbolt ships as a single unit and is installed by locksmiths, carpenters, or general contractors during door hardware replacement or new construction.

This deadbolt is appropriate for residential entry doors where a single cylinder keyed exterior lock with thumb-turn interior operation is required. The dual backset compatibility allows it to fit door preps that follow standard ANSI spacing for both older and newer construction. It is sold individually and is suited for single-door installations in homes, apartments, and light commercial entries.
