Emtek 8423US4 Modern Disc Single Cylinder Deadbolt Satin Brass

Product Description

The EMTEK 8423US4 is a single cylinder deadbolt featuring a Modern Disc trim design, finished in Satin Brass. It is designed to secure residential entry doors and is compatible with doors measuring 1-3/4 inches thick. The deadbolt ships with two backset options — 2-3/8 inches and 2-3/4 inches — covering the most common door prep configurations found in residential construction. The cylinder operates from the exterior with a key and from the interior with a thumb turn. This hardware is typically installed by finish carpenters, general contractors, or experienced DIYers during new construction or door replacement work.

The 8423US4 is suited for residential interior and exterior door applications where a modern, minimalist aesthetic is required alongside reliable deadbolt security. The Satin Brass finish integrates well with contemporary and transitional design schemes. The included dual backset compatibility makes it adaptable to standard pre-hung door units without additional hardware modification. Custom assembly is performed at the manufacturer's Southern California facility, with each unit sold individually.
