  • Gearhead motor; perfect drive alignment.

  • Quality roller drive chain with minimum ultimate tensile strength to 6100 lbs.

This style of door operator utilizes a continuous loop of heavy roller chain for control of door movement. The chain is driven by the drive sprocket of the power unit and held at the proper tension at the other end by an idler sprocket in a take-up wall bracket. Doors are attached to the chain with heavy duty brackets. An emergency release is attached to each bracket for manual operation.
