PART NO: 51621. REVISION 6 - OCTOBER 2016
opening requirements
The door is designed to be mounted behind the
opening, therefore you will need to measure and
check:
OPENING WIDTH
- As the door overlaps each side by
25mm or more, the door should be 50mm wider than
the opening. A wider door can be fitted as long as
additional sideroom and fixing is available. If the door
is too narrow, the opening should be reduced by
fitting jambs to the inside of the opening.
OPENING HEIGHT
- The door will fit any opening
height up to the marked door size (the guides can be
cut to suit). After installation the walk-in clearance,
under the door when installed, will be reduced by
approximately 80mm.
LEVEL AND PLUMB
- The door must be installed in an
absolutely level position, if opening is not level and
square, appearance and/or sideroom requirements
will be affected. Where jambs are out of plumb, extra
sideroom or opening modifications may be required
to allow the door guides to stand back from the
opening edge. The floor should be level or recessed
across the opening to avoid gaps.
STRUCTURAL SUITABILITY
- Ensure the opening is strong
enough to support the door. If unsure, consult builder
or professional door installer.
SIDEROOM
- A minimum of 75mm (100mm desirable)
of sideroom is required behind the opening and
should extend above the head to allow for bracket
fixing. Sideroom on one side of 115mm is required if a
B&D Controll-A-Door
®
garage door opener is to be
fitted now or in the future.
OBSTRUCTIONS
- Ensure that the surface where the
door will be fitted is flush and smooth, and the area
behind the opening is free from any protrusions.
HEADROOM
- See diagram. If the door is installed
lower into the opening than shown, additional loss of
walk-in clearance will result. The fitting of a head infill
panel may also be necessary, in order to improve the
external appearance.
