The Cast Iron Chain Hoist is designed for manual operation of compatible roll up doors and rolling steel door systems.
This chain hoist works with torsion spring rotating barrel assemblies that require a manual chain-driven lifting system. The 4:1 gear reduction helps reduce the manual force needed to operate the door.
This unit comes pre-mounted and is available in 1.25″ bore size only. It includes a 48-tooth door gear and 12-tooth hoist drive gear for compatible roll up door applications.
The set includes the hand chain, key, and set screw needed for installation.
