Important Notes:-
The following table shows the
minimum
amount of "Working Space"
that is
required for the
normal
installation of
standard size
Sectional
doors. If the
space available is
less
than that stated
here, then
special equipment
may be
required to undertake the installation.
Certain assumptions have been made,
i.e.:-
1)
The opening heights are
2135
mm for
standard doors or
2540
mm for
caravan height doors.
2)
The structure is level, square, plumb
and true as the case may be.
3)
For Sectional Doors, the door panel
overlaps the opening by no more
than
30
mm at the top and sides.
Contact your local dealer
for advice
before
committing yourself to a difficult
installation!
