How much room do I need above the garage opening?
The door curtain is mounted on brackets above the garage opening and to
allow maximum drive through height, the minimum headroom required is
shown in the table below.
If insufficient headroom is available to allow the door roll to be fitted fully
above the opening, the door may be fitted projecting down into the opening
up to a maximum of 100mm without the need for a fascia. If the door
projects down by more than 100mm a fascia (not supplied) will be required -
see figure 1.
Note: 10mm more headroom is required to install the door than is needed
to operate the door once installed. If the available headroom is right at the
minimum, the bracket can be fixed 10mm lower whilst the door roll is fitted
and tensioned and then tapped up by 10mm once the door is installed to
give full clearance with no hangdown.
*The minimum headroom but will require bracket position adjustment
during installation to achieve full opening height. (see page 9)
**The minimum headroom that requires no bracket position adjustment
during installation to achieve full opening height. (see page 9)

Do not remove any wrapping, or steel protective outer
wrapping if fitted to your door, until instructed.
(a) Door package and its contents
should be checked for obvious damage before removal of
protective outer wrapping (If on your door).
(b) The door should only be fitted after any plastering of the area
has been completed. Plaster splashes will damage the pre-finish
on the curtain and cause premature wear of the nyloflex within
the guides.
(
c) The door must be fitted square and level irrespective
of the shape of the opening. On no account should any
compensation be made to suit an irregular opening
