INSTALLATION STEP 4

Hang the Opener

THE OPENER MUST BE SECURELY FASTENED TO A STRUCTURAL SUPPORT OF THE GARAGE.

Three representative installations are shown. Yours may be different. Hanging brackets should be angled (Fig.1) or crossed (Fig.2) to provide rigid support. On finished ceilings (Fig.3), attach a sturdy metal bracket (not supplied) to ceiling joists before installing opener.

PROCEDURE: Measure the distance from EACH side of the opener to the 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 bracket holes. Drill 3/16" pilot holes in structural supports. Attach flattened ends of brackets to the supports with 5/16"x1-7/8" lag screws.

Lift opener and fasten to hanging bracket as shown.

Check to make sure the T-rail is centered over door. REMOVE the 2x4.

Operate the door manually. If door hits the rail, raise header bracket.

Grease the top and underside of rail surface on which trolley slides. A tube of grease is supplied.
