Product Details
Single Deadbolt, 2 Inch Backset, Heavy Duty
Heavy duty deadbolt designed for Atrium style hinged swing patio doors. The 2 inch backset is a non-standard measurement for patio door applications and suits low-profile frame conditions. Throw projection is minimal — 9/16 inches (14.3mm) outside and 1 inch (25.4mm) inside — making this suitable where door frame depth is limited.
Direct replacement for legacy Amerock and National deadbolts on comparable Atrium door systems.
