Painter s Pyramids work much like a board studded with nails, but unlike nailboards, they can be rearranged quickly for various projects, they won t leave prick marks in the surface, and they nest into a neat, compact stack for storage. This new, improved version features screw tabs for securing the pyramids when using lazy susans and other finishing fixtures. In addition, they feature a locking tab so you can "chain" or "nest" the pyramids together to create a stable surface and distribute the weight over a broader area. Molded with a slightly rounded tip from a non-stick, non-reactive polymer, they will not mar the finish or the wood. Each pyramid supports up to 200 lbs and stands about 2" high.
