Rockler's vacuum clamp pod kit holds workpieces securely from underneath, allowing unobstructed access to the entire surface for tasks like edge routing, sanding, planing, and CNC carving. The clamps work on nearly any workpiece with at least one flat face, as small as about four inches square. Incorporating a ball valve that allows individual pods to be used without the need to remove others from the series, the pods can be connected to additional pods for applications where a wider clamping base is needed. Priced at $59.99, the kit includes foam gaskets, 8ft. of plastic tubing, and necessary brass fittings.
