Installation Step 6

Hang the Opener

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.		The bracket and fastening hardware
are not supplied.
• Measure the distance from		each	side of the opener to
the structural support.

•Cut both pieces of the hanging bracket to required lengths.

•Drill 3/16" pilot holes in the structural supports.

•Attach one end of each bracket to a support with 5/16" - 18x1-7/8" lag screws.

•Fasten the opener to the hanging brackets with

5/16" - 18x7/8" screws, lock washers and nuts.

• 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).

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