2.0 INSTALLATION
2.1 FIXING REQUIREMENTS
For attachments to good timber work, coach screws are the standard fi xings supplied with B&D Roll-A-Doors. When installing onto
masonry special fi xings will be required. PLEASE REFER TO THE SEPARATE B&D FASTENER RECOMMENDATION GUIDE OR SEEK
FURTHER ASSISTANCE.
It is the installers’ responsibility to ensure that the fi xing method is sound.
When deciding the fi xing method, dynamic loads on door brackets as well as the door weight must be considered.
All measurements are in millimeters and are minimum unless otherwise shown.
NOTE:
It is not recommended that doors fi tted in restricted headroom be fi tted with openers.

*C2, E2, G Dimensions are for Restricted Headroom Installations Only, (G = Height of guide top above bracket arm see Step 4).
Dimensions are recommended and suit Normal Headroom Installations, top of guide will be level with top of bracket arm (i.e. G).
B&D Firmadoors are normally installed to operate behind the
opening, overlapping as described in the dimension sketch,
opposite. Openings should therefore have suffi cient return on both
sides to accommodate the support brackets and door guides, with
necessary working clearances.
The door is supported on brackets above the opening at each end
and requires headroom for the door to nylon running strip up in
(see Dimension Panel). Consequently, piers or door posts must
continue up past the top of the opening to provide fi xing for the
support brackets.
It is preferable that lintels (or ‘heads’) be built fl ush with, or slightly
forward, to the back of the door posts if possible. This avoids an
excessive gap between the door and the lintel, while allowing
suffi cient working clearance to prevent the door rubbing against
the back of the lintel.
DOOR SIZE – Width:
The door curtain should be 100mm (see
Dimension Panel) wider than the opening. However, a wider than
normal door can be fi tted by allowing the door to overlap further
on each side, providing the additional sideroom is available.
Height:
A door can not be installed higher than its maximum size;
however, it can be installed in a lower position (providing the door
guides are cut to suit – as shown later).
If the opening is too high, the door should be installed at the
maximum door height position and the opening reduced or treated
as shown in Step 2.2 under the heading “Bracket Fixing”.
WARNING!
No guarantee will be given or responsibility accepted
by the manufacturers if the door is not installed as instructed. For
satisfactory door operation please follow the instructions carefully.
NOTE:
If the chain mechanism is fi tted to the R/h side A1&A2
detail is reversed and 40mm must be added to the A1
measurement.
