BESSEY STB100M Deep-Throat Screw Clamp 1000mm Clamping Width 175mm Throat Depth

In a professional woodworking shop, a cabinetmaker needs to secure a large panel for edge banding, but standard clamps cannot reach far enough over the workpiece. The BESSEY STB100M deep-throat screw clamp solves this with a 175 mm throat depth, allowing firm clamping of wide boards and panels. Its 1000 mm maximum clamping width accommodates large assemblies, while the trapezoidal thread spindle delivers up to 6,000 N of force for secure, vibration-resistant holding. The ergonomic wooden handle provides comfortable operation, and the swiveling, non-slip pressure plate adapts to angled surfaces. High-quality cast iron jaws and a galvanized steel rail ensure durability in demanding environments.
