2. alternative bracket fitting
An “A2”extended leg bracket should be used in
conjunction with the standard “A” style bracket-under
the following circumstances:
a) If brickwork is old, or in any way suspect.
b) If floater bricks are present, but sound fixing lower
down the brickwork is available.
c) When fixing to honeycomb or semi-hollow bricks.
d) Where RSJ interferes with “A” bracket.
NOTE: Where old brick work with lime mortar is
encountered, or any doubt exists as to the holding
power of the masonry work, a timber frame, which
continues above the head for bracket fixing, should
be fitted on the back surface of the opening.
When fixing brackets to timber, the heavier coach
screws supplied are usually adequate. In some cases,
especially where timber is very soft, old or insecure,
coach bolts should be used.
1. alternative headroom fitting:
appearance improvement
If headroom is less than 250mm, a head infill panel
should be fitted to improve the external appearance
of garage opening. Note that the head infill panel
must not be installed too close to the curtain face.
B&D Head lnfill Panels are available to match or
contrast with your door(s).
