The Dura-Bench Ultra plastic bench top from Southwest Agri-Plastics is engineered to replace wood, wire, and expanded metal on greenhouse benches. The 2 ft. x 4 ft. (8 sq. ft. nominal) non-porous polypropylene plastic panel is designed with 1.1 in. x 2.1 in. rectangular holes for easy cleaning, and is engineered to interconnect with other Dura-Bench Ultra panels with nylon clips to create a smooth, flat bench surface. The Dura-Bench Ultra is durable, smooth, non-porous, and allows trays, flats, and pots to slide across the surface without snagging.
