Emtek 8569US19 Square Single Sided Deadbolt Flat Black

Product Description

The EMTEK 8569US19 is a square single sided deadbolt designed for residential and light commercial door security applications. Built for 1-3/4 inch doors, it ships with both a 2-3/8 inch and a 2-3/4 inch backset to cover the two most common door prep configurations without requiring a separate purchase. The flat black (US19) finish delivers a clean, uniform appearance suited to modern and transitional door designs. At 1.5 pounds, the hardware is solid in hand without being difficult to maneuver during installation. Locksmiths and finish carpenters are the primary trades involved in fitting this unit.

This deadbolt is intended for single sided applications where a keyed or thumbturn entry is needed on one face of the door only. Typical installs include entry doors, utility room doors, and interior doors requiring one-way security. It fits standard 1-3/4 inch door thickness, which covers the large majority of residential exterior and interior door stock. The included dual-backset option accommodates both new-construction and retrofit scenarios where the door prep may vary from job to job.

Installation Notes

Installation is typically performed by a licensed locksmith or experienced finish carpenter. Before beginning, confirm the door bore and backset measurement match the selected configuration, and ensure the door edge prep accepts the deadbolt latch plate. No special tools beyond a standard drill, chisel set, and screwdrivers are required for most installations. Follow local building codes for exterior door security hardware where applicable.
