• The Model 200-D Sectional Door Chain Hoist is a direct-drive manual chain hoist designed for compatible sectional overhead garage doors using a 1" keyed shaft. This hoist allows a properly balanced commercial or industrial sectional door to be opened and closed manually with a hand chain.

  The Model 200-D is commonly used on commercial overhead doors, warehouse doors, service bay doors, loading dock doors, storage facility doors, and industrial sectional doors where manual chain operation is required. It is a practical replacement or retrofit part for commercial door technicians, maintenance teams, property managers, and overhead door service companies.

  This chain hoist is designed for 1" shaft applications and fits installations with a minimum 3-3/8" offset from the wall. The shaft must be keyed for proper installation. The kit is commonly supplied with 26 ft of galvanized hand chain, one chain keeper, one 1/4" shaft key, and two shaft collars, depending on supplier packaging.

  Compatibility & Fitment

  The Model 200-D chain hoist is intended for compatible sectional garage doors with a 1" keyed torsion shaft and sufficient side-room/offset clearance. Before ordering, confirm the shaft diameter, shaft keyway, wall offset, door size, door weight, drum setup, spring balance, and required hand-chain length.

  This model fits a 3-3/8" minimum offset. It should not be confused with the Model 2000-D, which is commonly associated with a 5-3/8" offset. Selecting the wrong offset can cause fitment problems or interference with the wall, track, shaft, drums, or other hardware.

  For doors higher than approximately 15 ft, additional hand chain may be required. Always verify the required chain drop based on the actual door height and mounting position.

  Installation Notes

  Install the Model 200-D according to the manufacturer’s instructions and the door system requirements. The hoist must be mounted to a compatible 1" keyed shaft with the correct offset clearance. Confirm that the shaft key, collars, chain keeper, and hand chain are installed securely before operating the door.

  The door must be properly balanced before using a chain hoist. A chain hoist is not designed to compensate for broken springs, incorrect spring tension, damaged cables, worn drums, bent tracks, or other unsafe door conditions.

  After installation, test the door through multiple full cycles. Confirm smooth operation, proper chain travel, secure shaft engagement, correct chain keeper position, and no interference with tracks, drums, cables, wall brackets, or surrounding equipment.

  Safety Notice

  Commercial garage doors and industrial sectional doors are heavy systems that operate with springs, cables, drums, shafts, and hardware under high tension. Incorrect installation or use of a chain hoist can cause serious injury, death, or property damage.

  This product should be installed only by trained garage door or commercial overhead door technicians. Never use a chain hoist on a door with broken springs, loose cables, damaged drums, bent tracks, failed bearings, or an unbalanced counterbalance system.
