Mounting Door Bracket and Arms
Step 11.1 - Alternative Mounting Option
The opener can be fastened to the roof by driving a bolt
through the C-Rail into a structural timber support. The bolt
head’s height must not exceed 6mm (Fig. 18).
Step 12 - Mounting Door Bracket
The door bracket comes in two parts. The bottom plate
with two mounting holes is used on its own for one piece
doors. For sectional doors, the top plate is placed over the
bottom plate and is fi xed with four (4) screws (Fig. 19).
a. Mount the door bracket, or bracket assembly, on the
door’s centre line one-third down the top panel (Fig.
19) using M6 or equivalent screws (not supplied),
b. STEEL DOORS ONLY: Bracket can be welded in
place.
NOTE: If in doubt about the door’s strength,
reinforcement may be added to the door’s
frame where necessary. Door damage may
occur if the bracket is installed on a panel
with insuffi cient strength. The opener’s
warranty does not cover damage caused to
the door and/or door panels.
Step 13 - Attaching the Arms
FOR SECTIONAL AND ONE PIECE DOORS WITH TRACK:
a. Assemble the bent and straight arms with bolts
and nuts supplied in the accessory pack (Fig. 20).
Always use both bent and straight arms.
b. Connect the assembled arm to the bracket and the
disengaged trolley with clevis and snap pins. The
angle “A” must be more than 10° (Fig. 20).
WARNING: Connecting the bent arm other
way around may damage the door.
FOR ONE PIECE DOORS WITHOUT TRACK
a. Assemble the bent and straight arms as shown in (Fig.
21) with bolts and nuts supplied in the accessory
pack. Always use both the bent and straight arms.
b. Connect the assembled arm to the bracket and the
disengaged trolley with clevis and snap pins.
c. If installing on a door with a bad wave action,
lengthening the arm will assist in reducing this effect.
IMPORTANT NOTE - If the manual release
handle is more than 1.8 metres from fl oor level
when the opener is installed, extend the handle
to a height less than 1.8 metres.
