3. Attach the Belt: Loop the belt through the pulley and around the motor sprocket. Use the provided tension system to adjust tightness.
4. Secure the Rail to the Motor Unit: Once everything is threaded and aligned, bolt the rail to the motor housing.

2: Mount the Header Bracket

3: Hang the Opener

1. Lift the Rail into Place: Insert the end of the rail into the header bracket.
2. Mount the Motor Unit: Use the supplied hanging straps or angle iron to suspend the motor from the ceiling. Ensure the unit is level.
