Tarp Surplus is your 1-stop shop for 20' x 40' Canopy Enclosure Replacement Kits. Our 5-piece kits include a zippered door, a solid back panel, 2 side panels and a valance top cover. They are designed to fit on your existing 18' x 40' frame and are an affordable alternative to purchasing an entire canopy kit. The cover and panels are made from extra-thick 12 mil polyethylene and are able to block unwanted sunlight, rain and debris from entering the space. The side panels extend from the roof of the structure to the ground and the zippered door closes securely.
Replacement canopy pieces are mildew resistant and provide extreme UV protection. The roof panel included in the kit is designed to provide an extra 6 to 8-inch overhang for maximum protection. The top panel of the canopy measures approximately 20' x 40' to accommodate the peak in your existing 18' x 40' frame. Our 20' x 40' enclosure kits are available in your choice of 3 colors. Please refer to the canopy diagrams below for proper measurements before ordering.
