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 your garage door opener will vary depending on your garage. Two representative
installations are shown. Yours may be different. Hanging brackets should be angled (Figure 1) to
provide rigid support. On finished ceilings (Figure 2), attach a sturdy metal bracket to structural
supports before installing the opener. This bracket and fastening hardware are not provided.
1. Measure the distance from each side of the motor unit to the structural support.
2. Cut both pieces of the hanging bracket to required lengths.
3. Drill 3/16" pilot holes in the structural supports.
4. Attach one end of each bracket to a support with 5/16"-18 x 1-7/8" lag screws (not
provided).
5. Fasten the opener to the hanging brackets with 5/16"-18 x 7/8" hex bolts, lock washers and
nuts.
6. Check to make sure the rail is centered over the door (or in line with the header bracket if the
bracket is not centered above the door).
7. Remove the 2x4. Operate the door manually. If the door hits the rail, raise the header
bracket.
NOTE: DO NOT connect power to opener at this time.
