Poly-Riser 48" x 23" panels provide a 1-3/4" height with a conventient flow-through grid design allowing workers to keep safely out of hazardous solvents, chemicals, and wet conditions. Build out horizontally with additional Poly-Riser panels to fit almost any space. No-tool assembly allows for easy modification and clean up of the work area. Made from UV protected high-density polyethylene, Poly-Riser is good for indoor or outdoor use. Can be cut to size with a circular saw or handsaw.
