TRUSS ASSEMBLY
(This section is to be used only for greenhouses that are over 14’ long.)
Trusses are usually installed after the sides, base, front, back
and ridge are bolted together. Make sure that the greenhouse is
temporarily braced
(see 4A on Aluminum Frame Assembly).
A. Lay the truss piece in the shape of an end wall.
B. Slide the center pieces into the top of the truss and bolt them
together.

TRUSS ASSEMBLY & INSTALLATION (IF REQUIRED)
The next step takes two people, one on each side. Carry the
truss to the center of the greenhouse and put the feet on your
foundation between the side base/sill

. Lift the top of the
truss towards the ridge and bolt it on

. Use the notch on
either side of the center.
(For lean to installations line up the top of
the truss 1

” off-centre of roof glazing bar and temporarily fasten with
a screw to the wall. This should be permanently lagged to the wall after
greenhouse is square and the purlin has no sags at the truss. The gap
between the underside of the bar and top of the truss should be 3.”)
Remove the truss bracket from the truss.
(It may also be in a plastic
bag.)
Unbolt the bar from the base. Slide the truss bracket into
the bottom of the glass bar
(long bar)

and slide it to the
place where there is a 9/64” hole drilled into the truss. Fasten it
with a screw. If the hole does not line up, you may have to drill a
new hole in the truss bracket
11
. Do this after all the glass bars
have been bolted together. To fasten the truss to the foundation,
use 1/4” x 2” leg bolts.
