Replacing a worn canopy costs far less than replacing a whole gazebo, and this 12 x 10 ft top is cut to fit a two-tier frame with a 3 x 2.5 ft upper vent. A waterproof PU coating sheds rain, drainage holes stop water pooling in the corners, and the vent between tiers lets hot air escape rather than building up underneath. The polyester is CPAI-84 certified flame retardant. Frame not included. Net weight 4 lbs.
