Product Description

The EMTEK 8457MB is a single cylinder deadbolt featuring a plate and flap trim design, built for 1-3/4 inch doors and supplied with both 2-3/8 inch and 2-3/4 inch backset options. It ships in a Medium Bronze finish and is custom assembled to order. The unit is suited for residential and light commercial entry doors where a keyed exterior cylinder is paired with a thumb-turn interior. Licensed locksmiths, carpenters, and general contractors are the typical installers. The package weighs 2.55 pounds and ships as a single unit.

This deadbolt is appropriate for standard residential entry doors measuring 1-3/4 inches thick. The included dual backset capability — 2-3/8 inches and 2-3/4 inches — allows it to fit the most common door prep configurations found in new construction and retrofit applications. The plate and flap trim configuration provides a finished appearance on both the interior and exterior faces of the door. Medium Bronze finish coordinates with a wide range of architectural hardware styles.

Do not force the latch or bolt during alignment — adjust the strike plate position if the bolt does not seat smoothly.
