Mounting Door Bracket & Arms
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.
24).
a. Mount the door bracket, or bracket assembly,
on the door's centre line one-third down the top
panel (Fig. 24) 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.
