The 8500HPC series sliding arm clamps are exclusive to BESSEY. These all steal bar clamp's have a unique, narrow throat depth which enables you to create up to 8500 pounds clamping force with a tool that is considerably lighter than the 7200 series with their 8 inch throat depth. Like the others in our high performance line, the 7200 series features the new improved MorPad for smoother, more efficient clamping. These clamps are made in Germany, in BESSEY's own factory from steel that comes from Bessey's own steel mill. BESSEY is the only clamp manufacturer with quality control from raw material to finished product. BESSEY created the first sliding arm clamp and to this day remains the category leader in both quality and design. BESSEY. Simply better.
