Header Bracket Installation
For a canopy door, the instructions (Figures 2A & 2B)
replace Step 13 in the Owner's manual which refer to
positioning the header bracket. If you have an inward
facing lintel, which does not allow the header bracket
to be fitted directly above the garage door, you should
refer to step Garage door with inward protruding lintel.
For dual track doors, install the header bracket
50mm (2") above the high point of door travel as
shown in the Owner's manual.
