Protennis starting clamp
Protennis starting clamp. New model 2019: with new diamond cutting directly on the faces, this model is proposed with new antagonist springs: them have been recalibrated and reduced from 3 to 2, a solution which, combined with the new diamond cutting, allows an immovable locking without any wear on the string. It is a multifunction clamp: start stringing, traction at the node, emergency extension.
