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 9" (23cm) 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. The clamp has 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.
