Installation
STEP 5 Hang the Garage Door Opener
To avoid possible SERIOUS INJURY from a falling garage door opener, fasten it SECURELY to structural
supports of the garage. Concrete anchors MUST be used if installing ANY brackets into masonry.
Hanging the garage door opener will vary depending on your garage. Below are three example installations.
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 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.
