Rated at 10 x 20 ft this replacement carport canopy cover drops over an existing frame to restore weather protection for cars boats RVs and outdoor workshops. The heavy duty polyethylene tarp is waterproof Uv resistant and tear resistant so snow melt rain runoff and summer sun all run off cleanly. Reinforced grommets line every edge and the included ball bungee tie-downs pull the cover taut against the frame bars eliminating wind flap.
