General Lock D662 626 234 IC Grade 1 Double Cylindrical Deadbolt (SFIC Keyway)
The General Lock D662 626 234 IC is a super heavy-duty Grade 1 Double 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.
Featuring the Double Cylinder function, this lock requires a physical key to throw or retract the deadbolt from both the exterior and interior sides of the door. This layout is critical for doors with glass panels or adjacent sidelights, preventing an intruder from smashing the glass and reaching inside to flip a standard thumb-turn. 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.
