At this point you will need to lift the structure onto a firm footing or the greenhouse base if you haven’t already done so.

There are 4 diagonal roof braces. You attach these to the point where the ridge bolts to the corner bars at the rear end. The
angle travels diagonally down to the first glazing bar at the eave/gutter. You fit one each side at the rear of the greenhouse.
11.
You can now attach the T-bar cantilevers, which bolt to the sidebars and roof as indicated in point 8.
Before tightening these cantilevers up make sure there is no sag in the ridge or outward bow in the eave. (Key point) If you do
have this problem you must straighten it out before tightening the cantilevers up. A bow or sag can easily be removed with 2
people pushing the gutters towards each other until straight, hold it in position whilst a third person tightens up the cantilevers.
The main structure is now complete and it must be lifted onto its base for securing down.
