This cast iron screw clamp is a powerful and robust tool for interior construction, rough construction, furniture and carpentry work, kitchen and shop fitting, as well as joinery and timber construction. It is made in a reinforced design, providing higher clamping force and greater clamping spans than conventional clamps. This allows for the secure and stable clamping of heavy workpieces. The ergonomically shaped wooden handle ensures fatigue-free working even during longer tasks. The stable hollow profile rail with ribbing offers a secure grip for the workpieces.
