Remove the attachments from two opposing corners of the shade sail. Unsnap a spring clip or chain from the D-rings on the shade sail corners and eyebolts on the corner posts. Untie both ends of a rope from both the shade sail D-rings and the eyebolts on two opposite corners.
Hold a turnbuckle with the hook openings on each end facing down. Hook one end on the shade sail D-ring and the other end on the eyebolt in a corner post. Attach one turnbuckle in each of the opposite corners that you detached in Step One.
Insert a flat-head screwdriver into the center of one turnbuckle. There is a slot in the center with two threaded screws on each end. Turn the screwdriver clockwise two revolutions to tighten the turnbuckle. Tighten the second turnbuckles two revolutions in the same manner.
Tighten one turnbuckle and then the second one alternately in this manner until the shade sail is equally tight between the two opposite corners.
