SECTION 6
Measure and cut a 150mm length of
punched angle iron with a pair of tin
snips.
Snip off the four corners of
the punched angle iron to
add a degree of safety and
neatness to the installation.
Align the punched angle iron
centered onto the garage door
centre line, and the perpendicular
line running along the center of the
horizontal face holes.
The horizontal face must face the
back of the garage. Secure the
punched angle iron to the ceiling
with suitable screws (depending
on the structural member of the
ceiling).
Ensure that the punched
angle iron is mounted
to a strong structural
member in the ceiling.
