INSTALLATION STEP 5
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. This
bracket and fastening hardware are not provided.
Measure the distance from each side of the motor unit to the 1.
structural support.
Cut both pieces of the hanging bracket to required lengths.2.
Drill 3/16" pilot holes in the structural supports.3.
Attach one end of each bracket to a support with 4.
5/16"-18x1-7/8" lag screws.
Fasten the opener to the hanging brackets with 5/16"-18x7/8" 5.
hex bolts, lock washers and nuts.
Check to make sure the rail is centered over the door (or in line 6.
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 7.
rail, raise the header bracket.
Grease the top and underside of the rail surface where the 8.
trolley slides with rail grease.
