Control holes

Control holes

When producing cistern tanks, it is necessary that the ventilation holes are diametrically located and to have a diameter of at least 50 mm. The internal sectioning walls and the bottom must be cut and suspension lugs should be placed. If possible, the internal walls should be visible from the control opening.
