The Abba Patio 10 ft. x 20 ft. Heavy-Duty Carport with Removable Sidewalls with 8 Legs, Dark Grey is built to last. This carport kit is built with higher gauge steel than most carports. That means it is heavier and will stand up to the wind and weather elements better than other carports. and that's just the beginning. It also comes with removable sidewalls and rollup doors and has 8 sturdy wide 1.5 in. Dia poles. All assembly accessories are included. The heavy-duty bungee cords tightly secure the tarp cover to the frame. Foot pads are installed to the canopy legs for added stability and easy access to secure anchor points.
