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 (not supplied)
to structural supports before installing opener.
PROCEDURE: Measure the distance from EACH
side of the opener to structural support.
Cut both pieces of the hanging bracket to required
lengths. Flatten one end of each bracket and bend
or twist to fit the fastening angles. Do not bend at
the brackets holes. Drill 5mm pilot holes in the
structural supports. Attach flattened ends of
brackets to supports with 5/16"x1-7/8" lag screws.
Lift opener and fasten to hanging bracket as shown.
Check to make sure T-rail is centered over door.
REMOVE 25mm board. Operate door manually. If
door hits the rail, raise header bracket.
