**Jaw opens to 4.0" wide for clamping on round or square stock.***
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 4.0 inch 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.
