The 7200 series extra heavy duty clamps are exclusive /unique to BESSEY. No other clamp manufacturer in the world makes a sliding arm clamp like these. The BESSEY 7200 series are the biggest, heftiest sliding arm clamps ever made. The 7200 series are designed so that a person can create up to 7,770 lbs of clamping force by hand. To make repetitive tasks easier with these heavy clamps BESSEY has integrated a wedge that can be used to lock the sliding arm in one spot along the clamp rail. 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 leader in the category in quality and design BESSEY. Simply better.
