Pulleys are design to make shade sail installations easy since they don't require additional hardware to hang the sail. They are made from 5052 aluminum with stainless steel hardware and graphite embedded bushings. Pulleys provide for easy install and take down by allowing the sail to be tensioned by hand.
The stainless steel 3/16" wire rope can be run through the perimeter pocket of the sail to create a complete loop using wire rope clamps to attach the wire rope to itself. When properly installed, the hardware transfers the tensile load from the corners to the center of the sail.
