When measuring your space, On each side of the sail allow a space between the corner of the shade sail and the mounting point that is at least 10% of the shade sail length. If one side of the shade sail has a 120 inch length, there should be at least 12 inches between the corner of the shade sail and the mounting point. This will provide enough room for mounting hardware, material stretch, and tightening the tension of the sail. This should be done for each side of the shade sail to ensure there is adequate room to tension the sail properly.
