The rafter to valley brackets are attached to the beam capping on
valley beams using six 12x20 hex head screws (figure 8.0) at the
appropriate locations.
For an end attached unit attach the second valley beam into the wall
or suspension bracket while using construction props to support the
opposite end. The gable rafters can now be fixed into the rafter to
valley brackets with two 12x20 hex head screws either side (figure 8.1).

For a side attached unit support the second valley beam at the
spacing determined in the section, ‘Gable Frame Assembly’ with
adjustable construction props. The gable rafters can now be fixed
into the rafter to valley brackets with two 12x20 hex head screws
either side (figure 8.1).
For units where rear and/or front header beams are required beam to beam brackets will be used. Place the bracket on the inside face of the
beam, aligning their curved flange with the top groove of the beam so that they clamp the beam fillers in place, fasten using two 12x20 hex
head screws (figure 7.0). Fasten the incoming beam either side with two 12x20 self drilling screws (figure 7.1).
If the unit is being installed with header beam/s attach the beam to
the frame work using beam to beam brackets. If fixed at the rear to
an attachment beam this beam becomes the header beam.
Attach gable beam brackets to the header beam and capping using
a minimum of eight 12x20 hex head self drilling screws, refer figure
9.0. Rafters are supplied notched at the base to fit the gable beam
brackets. Rafters are fastened inside the gable beam brackets with
a minimum of three 12x20 hex head self drilling screws either side
as shown in figure 9.0.
