This replacement canopy cover fits gazebos that were sold at Home Depot for the past several years, manufactured by SunJoy Industries, named the Sunjoy Leaf Gazebo. The distinct mark of the gazebo that this canopy was designed to replace is the leaf pattern design that is on all four corner posts. The Sunjoy model numbers of the gazebos are GZ077PST and TGZ077. Garden Winds recommends that you purchase this canopy only if you have this particular gazebo. This canopy will not fit any other gazebo. This is a CORNER POCKET designed gazebo replacement canopy top cover. This durable polyvinyl top cover has a two-tier ventilated top construction. The top tier measures 36" x 36", the bottom tier measures 129" x 129". The corners and sides of this canopy has "pockets" for the roof bars/rods to be inserted for a snug fit. Please view enlarged picture for a better viewing of the corner pocket design.
