Our Vinyl Patio Enclosures are designed to hold tight to your structure in bad weather. Our Wind-Load system that is rated for 65mph loads holds very securely which will increase the usability of your patio enclosure system year-round as it can be deployed more often than other patio enclosure systems. The wind-load system includes many features such as industrial grade curtain zipper connections, welded bottom, adjustable tie-down assembly, vertical (zippered) closures or weather flaps, aluminum tracked header with welting, filler flaps, welded stainless steel clip and D-Ring, and a nickel plated brass spring loaded trigger snap.
