Down-thrust clamps GN 9192 are compact clamping elements for quick and secure clamping in tool and fixture construction. Rotating and tightening the clamping screw or the adjustable hand lever moves the clamping arm downwards to clamp the workpiece. The clamping arm can be swiveled 360° by hand so that workpieces can be inserted and removed from above quickly and easily. The thread on the clamping arm d3 can be used for positioning elements and clamping pads
