Emtek 8455US19 Low Profile Single Cylinder Deadbolt Flat Black

Product Description

The EMTEK 8455US19 is a low profile single cylinder deadbolt finished in flat black, designed for installation in 1-3/4 inch doors. It accommodates both 2-3/8 inch and 2-3/4 inch backset configurations, giving installers flexibility across standard door preparations. The deadbolt is sold as a single unit and is suited for residential entry doors where a clean, low-profile trim style is specified. Licensed locksmiths, general contractors, and finish carpenters are the typical trades installing this hardware. At 2.35 pounds, the unit is solid in hand without being cumbersome to work with during installation.

This deadbolt is appropriate for residential exterior and interior doors requiring single cylinder deadbolt security. The flat black US19 finish coordinates with contemporary and transitional design schemes. The dual backset compatibility — 2-3/8 inches and 2-3/4 inches — covers the two most common door bore preparations found in residential construction, making it a practical stocking choice for installers working across multiple job sites or new construction projects.

Installation Notes

Installation is performed by a licensed locksmith, finish carpenter, or general contractor following standard door hardware procedures. Ensure the door bore and edge bore are clean and free of debris before fitting the deadbolt chassis. Verify backset measurement before installation — switching backset after initial fit may require re-boring the door edge. Follow all applicable local building codes for residential entry door security hardware.
