Bessey Tools VarioClippix® 2 x 4 in. Variable Spring Clamp is a clever variation on the standard spring clamp. This innovative clamp features an adjustable upper jaw that opens as wide as 3 inches, making it versatile enough to perform the work of four different standard spring clamps. The moveable jaw allows you to quickly and easily adjust clamping pressure from maximum force to almost no force, for delicate applications. Designed for comfort, the handles are made with a two-component, soft, anti-slip material. Additionally, soft pads on the tips prevent marring of your workpiece, ensuring smoother and straighter clamping every time. Model Number: XV5-100
