General Lock D660 626 234 IC Grade 1 Single Cylindrical Deadbolt (SFIC Keyway)

The General Lock D660 626 234 IC is a super heavy-duty Grade 1 Single Cylinder Deadbolt prepped specifically for a Small Format Interchangeable Core (SFIC) system. Engineered to meet the highest performance standards set by ANSI/BHMA, this heavy-duty mechanical deadbolt provides top-tier physical security and cycle life for high-traffic commercial, institutional, and industrial facilities.

This model features the Single Cylinder function—operated by an SFIC key on the exterior and an ergonomic thumb-turn on the interior to ensure immediate, tool-free emergency egress. It comes configured "Less Core" (SFIC Prep), meaning it is ready to accept a preferred interchangeable core, allowing you to seamlessly integrate it into your facility's existing master key system without discarding hardware. Finished in an architectural US26D Satin Chrome coating with a 2-3/4" backset, this deadbolt fits standard commercial door preparations and supports door thicknesses up to typical commercial specifications.
