Magswitch Pro Table Featherboard Magnetic 81101302 Right-Side Vertical. The Magswitch Pro Table Featherboard is a professional woodworking accessory designed to improve cutting accuracy on table saws and band saws. This vertical featherboard applies downward pressure to hold materials firmly in place during cuts, preventing thin stock from lifting or bending. Two powerful 30mm magnets provide 150 pounds of holding force and attach directly to any steel table saw fence or steel tabletop surface. The compressible gaskets ensure excellent grip when the magnets are engaged. The reversible design allows use on either side of the workpiece, and multiple featherboards can be interlocked to apply force at multiple points.
