INSTALLATION STEP 5
Hang the Opener
The opener must be securely fastened to a
structural support of the garage.
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 a structural support before installing the opener.
1. On each side of opener measure the distance from
the opener to the structural support (or ceiling).
2. 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 bracket holes. Drill 4.5mm (3/16") pilot holes in
the structural supports (or ceiling). Attach flattened
ends of brackets to supports with wood screws.
3. Lift opener and fasten to hanging brackets with
screw, lock washer and nut. Check to make sure
rail is centered over the door.
4. Remove 25mm (1") board. Operate door manually.
If door hits the rail, raise header bracket.
5. Use rail grease and lubricate inside surface of rail.
