Install Sun Shade Sail in the Backyard

1,Locate the attachment points you want to use for your sail cloth. In general, many sun shade sail cloths are attached to the back of the house at two or more points and to a distant post or tree. The square sun shade sail will be 12 inches smaller in all directions from the attachment points.
2,Install the attachment points to the house. Most sails are sold separate from hardware and the hardware is custom-selected for your application. Hardware is available to attach to the corner of the house using a corner bracket and lag bolts; attach to the rafter tail with a rafter bolt; attach to a wall stud with a long bracket and lag bolts; attach to a header above a door or window with a 4-hole pad eye and lag bolts; and attach with a 6-inch eyebolt to a galvanized post.
3,Follow the specific hardware directions for correctly mounting your attachment points to your house, posts, trees or distant points. If you are installing a post to act as a third attachment point away from the house, dig your post hole to 1/3 the length of the finished post and use gravel and concrete to anchor the post to the ground.
4,Attach the triangle sun shade sail to the attachment points by loosening the turnbuckles to the most open position. A turnbuckle is loosened by unscrewing it. Attach one shackle end of the turnbuckle to the attachment point and the other to the sail. Connect all three points. Extend the distance from the turnbuckle to the sail with chain if necessary. Turnbuckles will allow you to tighten the sun shade sail by simply turning the turnbuckle as needed.
5,Use D-shackles at the house side attachment points and a low stretch polyester rope on the third (post) side. A D-shackle is a U-shaped loop with two threaded holes at the ends of the U. There is a pin that is threaded to connect into the two holes. This configuration allows you to use the rope to tighten the sail or extend the attachment point across the yard to a distant tree or building. Follow the manufacturer’s recommendations for specific hardware and installation tips for your specific sail.
