7 Make sure the end hoops are set approximately 5cm higher than the inner hoops. (The inner hoops will
be raised later to tension the polythene.) The end hoops should be approximately 18cm above ground
level. Lock in place with the A20 fittings.
8 Slot the ridge tube into the E25 fittings,
starting with the plain-ended ridge tube.
Set the end of the ridge tube flush with the
E25 fitting and tighten the bolt to secure in
place.
9 Slot a swaged ridge tube into the end of
the previous ridge tube until you reach the
end of the polytunnel. Tighten the bolts in
the E25 fittings to secure the ridge tubes in
place.
10 Insert a plastic plug into each end of the
ridge tube.
11 Fit the four corner diagonals. Fix to the
KH20 fitting on the foundation tube first
using an M8 x 30 bolt & nylock nut. Then
fix to the KH25 fitting on the end hoop.
Tip! Put the bolts through from the outside so
that the thread of the bolt doesn’t
protrude into the polythene.
12 Set the end hoops so that they are vertical (looking from
the side) by adjusting the position of the KH25 fittings.
