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.
