NOTE:

Fittings and Blind Screws.
It is possible to change suction cups simply by pulling them off the fittings. It might be a bit challenging to
remove the 15 mm Diameter vacuum cups. As suggestion try to stretch the silicon to one of the sides and
then pull it out.
Unused holes can be blinded using a blind screw, and each fitting can be changed to a diffe rent type to
match the desired suction cup. The fittings and the blinding screws are mounted or dismounted by
screwing (2Nm tightening torque) or unscrewing them with the provided 3 mm Allen key.
.
The thread size is the commonly used G1/8"; allowing for standard fittings, blinders and extenders to be
fitted directly to the VG grippers.
