How deep do shade sail posts need to be?
Post Supports for Mounting Sails:
Footing depth should be a minimum of 36 inches deep and 30inches square. For example, if your post height is higher than 8 feet, we recommend a hole depth 40% of the height above ground.
Do shade sail posts need to be angled?
Ideally, they should be installed at an angle of 10 degrees for steel and 20 degrees for timber posts. The angle should be away from the shade sail, so account for the angle and the length of the turnbuckles when you dig your post holes.
How do you attach a shade sail to a tree?
Slip a snap hook over both hooks on one of the bungee cords. Attach the turnbuckle to one end of the snap hook and the sun sail grommet to the other. For spanning larger spaces, attach the turnbuckle to your chain or rope before hooking it to your snap hook with an S hook.
