Professional Screw Clamp 45°/90° (Item No. 2-160630, also known as S2-160630), replaces standard screw clamps with 45° or 90°. It sets new standards due to its infinitely variable adjustment range from 0°-360°. To ensure safe fastening of any welding element, the prisms are interchangeable. For suitable prisms, see page 576. The dimensions of the appropriate flat bar are 20x13 mm. The new handwheel on the cast iron cross
enables height adjustment within seconds.
