Two representative installations are shown. Yours may be different. Hanging brackets should be angled, Figure 1, to provide rigid support.

Measure the distance from each side of the opener to the structural support.

Cut both pieces of the hanging bracket to required lengths.

Check to make sure the T-rail is centered over the door (or in line with the header bracket if the bracket is not centered above the door).

Remove the 2x4. Operate the door manually. If the door hits the rail, raise the header bracket.
