A single sliding arm clamp can do the work of many different sizes of "C" clamp and, can do it nine times faster. The 1800 and 2400 series of bar clamps are regular duty clamps within the Bessey "ALL STEEL" line-up of clamps. These series of clamps feature some key improvements. Each series has a sliding arm design engineered for more efficient force transmission and both have a patented rail profile design for enhanced strength where it matters most. They also have the patented Bessey MorPad. This contact pad has significant high high-tech features to reduce internal friction and enhance a clamp's service life. Designed and 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.
