Hang an INFRANGE mesh screen on your fence line and a March gust crosses the weave instead of dragging the posts sideways, because every screen and sail passes air and water. Not one of them is waterproof, and that trade is the whole design. You strung a tarp there last summer, and August left pooled water, a sagging middle, torn corners.
Hang the mesh instead and the same storm drips through to the deck boards while your posts stay plumb. Zip-tie the screen to standard chain-link through brass grommets, matching ordinary post runs. Clip the sail's D-rings to two posts and a structurally sound house wall, and the deck has shade by dinner.
Watch your side yard go from bare rail to 90% blocked in the length of one afternoon, and the 3-year limited warranty on core screens and sails outlasts the one-year terms stamped on most import listings.
Check the rating before you order: the mesh screens and sails ship Not Water Resistant, so a July downpour comes straight through the weave. Push the solid vinyl pickets into soil along a porch edge if you want a physical barrier instead of a sightline block.
