The Heavier Density, writeable surface Valve Box Plug is constructed out of 2.2# closed cell polyethylene foam with an MDL surface that will accept permanent marker.  The WVBplug fits a standard valve box and is effective in keeping dirt, rocks, and debris from collecting in the bottom.  The 5/16” braided polypropylene highly visible handle allows for easy removal. The WVBplug is cut with a slight taper for easier installation but not compromising a snug fit that will keep the plug at the desired height in the valve box.
