INSTALLATION STEP 5

HANG THE 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.
Three representative installations are shown. Yours may be different. Hanging
brackets should be angled (Figure 1) to provide rigid support. On finished ceilings
(Figures 2 and 3), 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"-9x1-5/8" lag
screws.
5. Fasten the opener to the hanging brackets with 5/16"-18x7/8" 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.
