Guide bar
You have a total of four beams: two
sections with pulleys and pre-mounted
rails, which point to the rear wall, and two
more beams rails also pre-installed, but
without pulleys. These belong in the front
area and are held up by the two vertical
support beams.
Fasten the two left beam segments to form
a guide beam. The same for the right
beam segments. For this purpose, three
screws of the size 8x80 for each side are
included.
Place the rear beam elements on the left
and right (using the key and groove of the
wall planks) so that the outer edge of the
rear wall is flush with the timber of the
guide beam.

Support and guide beams
Now place the two support beams in the
specified positions under the guide beams
and screw them tightly through the bar
from above. (Washer and M16 screw).
Fasten the cross beam between the two
guide beams. They are screwed with four
screws.
Always construct your guide beam / cross
beam and support beams with a spirit
level.
Also check the straight and parallel
alignment of the two guide beams.
Verification of all horizontal and vertical
dimensions is very important for smootly
running roof section.
We recommend size M8 concrete anchors
to fix the columns to the ground; available
in your local hardware store.
