-Measure frame diagonally from corner to corner as shown
in figure 7. These Dimensions must be equal in order for
the fame to be square.
-It is extremely important to sight frame from all corner to
ensure it is not twisted across. Shim frame under any low
side. The maximum slope tolerance is 5mm per linear
meter in any direction.

shimmed, weld or secure the frame to the roof deck.
