Step 6: Truss Installation
Trusses are 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).

and
D. Bolt on the cross brace (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
towards the ridge and bolt it on
of the center. There are three notches in the ridge because if the
polybars have already been installed with the truss bracket facing
one way, you can bolt the truss to either notch without having to
turn the truss bracket around. Sometimes the installers put in all
the polybars first and slide the truss bracket in beforehand.
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 polybar (long bar)
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
been bolted together. To fasten the truss to the foundation, use
1/4" x 2" leg bolts (see extra pictures on page 20).
