ONE-PIECE DOOR WITHOUT TRACK
• With the door fully open and parallel to the floor,
measure the distance from the floor to the top of
the door.
• Using a stepladder as a support, raise the top of
the opener to this height.
• The top of the door should be level with the top of
the motor unit. Do not position the opener more
than 50mm above this point.
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 centred 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.
HARDWARE SHOWN ACTUAL SIZE
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.
