BESSEY engineers have combined sliding arm technology with the common spring clamp to create the "VarioClippix". The average sized hand struggles to operate even a 3 inch capacity traditional spring clamp; however, BESSEY has been able to create spring clamps with up to 6-1/2 inches capacity that can be easily operated with one hand. Rapid-action, polyamide, sliding jaws infinitely adjusts to fit project … the clamping capacity of a 6" spring clamp with the comfort of a 2" clamp. BESSEY. Simply better.
