2.2 BRACKET FIXING
Check the opening dimensions to ensure you have the correct
door size. Check fl oor and lintel levels and work from the lowest
side or from the side with the least headroom. Mark out fi rst
bracket after checking dimension panel for height of brackets
above lintel, E1 for normal headroom installation and E2 if
headroom is restricted. (If insuffi cient headroom, measure down
from ceiling or obstruction using dimension C1 or C2 and mark a
new line and treat as the lintel). Mark out one bracket, drill and
fi x after allowing suffi cient side clearance for door curtain Using
a water level or a straight edge and spirit level, transfer position
of top of fi rst bracket arm to opposite side of opening, then
mark, drill and fi x second bracket. (
NOTE:
the brackets must
be perfectly level for correct door operation). Also ensure that
the brackets are secure and the correct fi xings have been used.

NOTE:
1. Where possible, and for best performance, doors should be installed in the normal headroom position. The restricted headroom
installation should only be used where headroom is restricted and is not recommended for electrically driven doors.
2. The bottom rail of doors below 2400mm high will hang below lintel and reduce walk in height by 65mm. For doors above 2400mm
high, the bottom rail will be fl ush with the lintel.
3. Where insuffi cient headroom exists and brackets are placed above a marked lintel line it may be necessary to fi t a false head or
lintel to improve appearance of the installation and to improve cover.
2.3 POSITION DOOR ON BRACKETS
With the door the correct way round (the curtain
rolls down the rear of the opening) carefully lift door
onto the brackets using block and tackles attached
to the door axles, or other suitable lifting equipment
– avoid curtain damage.

ALTERNATE METHODS OF ATTACHING BRACKETS AND GUIDES
For Brackets:
Use six 10mm (3/8”) bolt size masonry
anchors; (dynabolts or similar).
For Guides:
Use the 40mm x 8mm (1V x 5/16”)
coach screws supplied, with a good
quality plastic masonry plug or suitable
masonry anchors.
NOTE TO BUILDERS:
Masonry blockwork should be properly
fi lled and reinforced if brackets are to
be mounted directly to blockwork with
masonry anchors. Where the blockwork
is not solidly fi lled but structurally sound,
long bolts should be passed through the
blockwork using suitable steel plates
under bolt heads.
Special consideration should be given
to brick type and construction of wall,
to ensure satisfactory fi xing e.g. welding
detail if fi xed to steel.
