A polymeric frame enclosing a rectangular aperture sized to receive in conforming fit a rectangular foundation panel on which a bee honeycomb is formed. The frame is formed by injection molding as an integral unitary piece with the interior volumes thereof foamed in the course of the molding process so that the exterior surfaces thereof remain smooth and impervious, allowing for easy cleaning and re-use. A plurality of alternatively sloped wedge projections are formed in spaced rows on each interior surface of the foundation panel receiving aperture between which the edges of the panel are captured by flexure relief.
