How to Hang a Sun Sail

Spread the sun sail on the ground, hem side down. Face each of the corners toward their intended anchor points, which can be the sides of buildings, trees and even concrete pillars. Each corner should already have a load-bearing anchor ring screwed into place.

Connect the two shackle anchor points first. The shackle is a small D-shaped locking buckle that connects the point of a sail to an anchor. Also called D-rings or Delta rings, these rings have locking pins that are opened and closed by twisting counterclockwise and clockwise.

Run a nylon rope through the third point in the sail and pull both ends through that point's anchor ring. Pull on the rope to lift the third point up and raise the sail. Pull the rope until the shade is close enough to connect the main turnbuckle. Tie off the rope to secure in place. The sun sail should already have a turnbuckle connecting the perimeter wire to the third anchor point, which is separate from the main turnbuckle.

Attach a D-ring to the third point of the sail. Attach the turnbuckle between the D-ring and the anchor point. Do not tighten the turnbuckle yet. Release and remove the nylon rope.

Pull on the loose end of the perimeter wire to take up slack. Push down on the round wire grips to secure in place. Use a screwdriver to tighten the wire grip. Run the loose hanging wire into the hem of the sail to keep it out of the way.

Turn the turnbuckle connecting the third point to the anchor point counterclockwise to tighten the sail. Turn by hand until tight, then use a small rod to lever it around a few more times for good measure.

Twist the turnbuckle attached to the perimeter wire to adjust the tension on the perimeter wire until taut.

Tighten the main turnbuckle a few more times to finish tension on the sun sail. Lock both turnbuckles into place by tightening the lock nuts into place at either end of the turnbuckles.
