The front carport door panel connects to the canopy frame by using ball bungees which loop through each grommet and around the frame poles. All front wall tarps are made of heavy-duty 12 poly material that is waterproof, rot-proof, and UV-resistant. Do you want to walk or drive through your carport? Then order two front carport replacement door panel tarps instead of one and attach one in the front and one in the back. This will allow you to open both panels for easy drive through capabilities. When ordering a full replacement carport kit, you will receive one rear panel and one zippered front panel. READ LESS
