You must remember to insert one extra bolt per cantilever T-bar brace and one per vent per bar. For
example the 8’ x 7’ would have 3 extra bolts on the middle bar on one side of the ridge and 2 on the
middle bar on the non vent side. In addition one extra bolt would be needed on the bar next to the
middle where you require the vent to go.
If you have purchased a partition with your greenhouse you will be 2 roof bars short of a full pack.
Omit one each side of the ridge at the point where the partition is to be situated i.e. at the same
place where you omitted the side glazing bars (see later text for partition details).
Before tightening the nuts that hold the roof bar to the eave you must ensure that the roof bar is tight
up against the small flange immediately above the gutter.
(Key point).
Failure to observe this point
and the previous one of keeping the roof bar tight up to the ridge could result in a slight outward
bow of the gutters and a slight downwards dip of the ridge.
8. At this point you will need to lift the structure onto a firm footing if you haven’t already done so.
9. On the 4’, 6’, 8’, 10’ and 12’ models there are 2 roof diagonal braces. On the 14’, 16’, 18’ and
20’ models there are 4. 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. If you have the longer house you put another 2 at the front
end.
10. You can now attach the T-bar cantilevers which bolt to the side bars and roof bars as indicated
above.
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, hole it in position whilst a third person tightens up
the cantilevers.
