Anti-slip bench protection dogs come in packs of eight. These 20mm shallow style bench dogs feature a small upstand topped with an anti-slip pad. In use they raise a workpiece slightly, enabling you to use a guide rail and plunge saw to cut through a workpiece and avoid scoring the top of your multifunction workbench. They fit into any 20mm chamfered dog hole and allow work such as sanding to proceed without mechanical clamping giving full access to a workpiece’s entire surface. Workholding is by friction alone.
