The BESSEY CL24 clamp is a versatile tool that can be a clamp or spreader. The special cantilevered design keeps the spindle & handle behind the clamp's rail to minimize obstruction over work piece. The V-grooved pressure plate is made of high grade cast iron and swivels up to 30 degrees. The CL24 clamp is easily reversible for spreading applications (spreading also requires optional CLS SHOE reverse pressure pad). Designed & manufactured for years of dependable service, these clamps are made in BESSEY's own German production facilities and, from steel that comes from BESSEY's own European steel mills. BESSEY created the first sliding arm clamp and to this day remains the category leader in both quality and design. BESSEY. Simply better.
