If fixing a Clearspan Gable on its end to a wall, valley beams are
fixed directly to the wall using beam to wall brackets. The rear gable
frame will need to be offset from the wall to allow the appropriate
bracket fixing. Wall brackets are positioned either side of the gable
opening at the spacing determined in the section ‘Gable Frame
Assembly’. The folded section on the tabs of the bracket is located
at the top (figure 6.0). The highest point of the wall bracket will be
15mm below the top of the beam. Mark the holes and drill using
an 8mm masonry bit. Fasten the bracket to the wall with two M8
masonry anchors to a minimum 65mm embedment. Locate the first

valley beam (beam cap on top) up into the wall bracket so the curved
flange locate against the top flute of the beam. The valley beam is
fastened to the wall bracket with two 12x20 hex head screws either
side in the pre-drilled holes while the opposite end is supported on
adjustable construction props. If required, additional hold down to
the wall may be obtained by using tie down brackets, refer figure 6.1.
A suspension bracket is used when a beam is suspended from
the fascia (figure 6.3). If fixing a Clearspan Gable on its end with
suspension brackets, the brackets are to be positioned either side of
After fixing all the brackets and channels, the attachment beam can
now be fixed into place.
Prop the attachment beam in position with the beam capping on top,
the beam will need to be located at a height on the bracket which
allows clearance between the Cooldek and the gutter. Fix to the end
plates of the rafter bracket using two M12 bolts, with the bolt head
on the attachment beam side. Insert spacers to prevent the beam
from crushing, and bolt in position, using nuts and washers. To
insert spacers drill 13mm holes through the attachment beam. Then
drill 16mm holes on the outside face only, but this time do not drill
all the way through. This will allow the spacer to slide in from the
outside and stop at the other side as shown in figure 5.
A cover flashing may be ordered as an additional option and custom
made to cover the exposed brackets and holes through the fascia.
Rivet flashings in place, figure 5.1 suggests a simplified flashing.
The attachment beam becomes the base for the attachment of the
Clearspan Gable unit.
Note: Do not over tighten bolts as this can lead to a visible
indentation due to the high gloss nature of the material. Refer to
figure 5.0 for fixing spacers.
