The Super Viser is an extremely strong and versatile clamp. It can mount securely onto round and square objects, or just about any unique shape up to 4 (11cm) in diameter. The jaw position remains fixed on one side of the clamp, enabling it to be mounted where limited space is available. The specially formulated grip pad provides a strong grip, yet protects the surface it's clamped around. Another Kupo innovation outfits this clamp with a hexagonal receiver that accepts the full compliment of Convi Clamp accessories. The Super Viser boasts an impressive load capacity of 66.1 lbs (30 Kg) and comes in a silver aluminum finish.
