The support base for the foundations must be constructed
above the level of the surrounding ground level; if necessary
raise the level a few centimetres.

ground surface.

It is essential that the foundation works be carried out
perfectly and that the plate be correctly positioned with
respect to the wing.

Warning
Leave the correct distance between the edge of the slab
and the gate surface (Fig.8).
