Your installation may be different. For ALL installations the garage door opener MUST be connected to structural supports. The instructions illustrate one of the examples below. 1. On finished ceilings, use the lag screws to attach a support bracket (not provided) to the structural supports before installing the garage door opener. 2. Make sure the garage door opener is aligned with the header bracket. Measure the distance from each side of the garage door opener to the support bracket. 3. Cut both pieces of the hanging bracket (not provided) to required lengths. 4. Attach the end of each hanging bracket to the support bracket with appropriate hardware (not provided). 5. Attach the garage door opener to the hanging brackets with the hex bolts, lock washers, and nuts. 6. Remove the 2x4 and manually close the door. If the door hits the rail, raise the header bracket.
