Emtek 8426US4 Single Cylinder Deadbolt Satin Brass

Product Description

The EMTEK 8426US4 is a single cylinder deadbolt designed for residential and light commercial door installations. It ships in a satin brass finish and accommodates both 2-3/8 inch and 2-3/4 inch backset configurations, giving installers flexibility across standard door prep sizes. The deadbolt fits doors measuring 1-3/4 inches thick, which covers the majority of exterior residential door stock. At 2.55 pounds, the unit is solid without being cumbersome during installation. Licensed locksmiths, carpenters, and general contractors are the typical trades installing this hardware.

This deadbolt suits exterior door applications where a keyed entry on one side and a thumb turn on the interior is the required configuration. The dual backset compatibility makes it straightforward to drop into existing door prep without redrilling. It is appropriate for single-family residential projects, multifamily unit doors, and light commercial tenant entries where standard 1-3/4 inch door thickness is used. No special frame modifications are required for standard ANSI prep doors.
