Designed for us by Riverdale Mills Corp. of Northbridge, MA. Our picture shows 5 panels for a complete composter with cover. We added the option of purchasing panels individually in case you’d like to use the panels in your vegetable or flower garden as verticle supports. The cost of each panel is $16, a whole set of 5 panels is $80. This is composting made easy with movable pre-cut modular panels 36″ x 36″, patterned with 1-1/2″ space openings for ventilation. Made of the highest quality, strongest and longest lasting 12.5 gauge high performance weather resistant PVC coated wire mesh available on the market. Riverdale’s PVC coated wire mesh is a welded and galvanized steel fabric coated with their proprietary marine grade PVC that is fuse bonded to the wire for ultimate protection. The PVC coating has a smooth thick uniform coating that does not peal or crack even when exposed to harsh marine environments.
