RDR Rolling Steel Door Chain Hoist Basic Kit – Head-Plate Mount, 26 ft Hand Chain

The RDR Chain Hoist Basic Kit provides manual operation for compatible rolling steel garage doors. Mounted at the door’s head plate, the hoist allows the user to raise and lower a properly balanced door by pulling the hand chain.

The kit includes a 50B12 sprocket with a 1-inch bore and 26 feet of hand chain. It is intended for rolling door installations that match the RDR mounting and drive arrangement.

COMPATIBILITY
Confirm that your rolling door accepts an RDR head-plate-mounted hoist. Check the mounting pattern, sprocket connection, shaft dimensions, and available clearance against the existing assembly or door manufacturer’s instructions.

Also verify that 26 feet of hand chain provides a suitable operating reach. This measurement is the total chain length; the installed loop has two hanging sides.

INSTALLATION
Installation should be performed by a qualified door technician. Secure the door before beginning work, verify the mounting and drive alignment, and route the hand chain according to the installation instructions. Check for smooth operation throughout the door’s travel and secure the hand chain in its keeper when required.

SAFETY
Use only with a properly balanced, freely moving door. Do not force a binding door or use the hoist to overcome broken springs or damaged hardware. Keep hands clear of sprockets and moving chain, and keep the doorway clear during operation.
