The Tethys is a compact, lightweight pulley designed to carry seamlessly on a harness and attach to a rope with ease. It features rotating side plates and a large attachment point that accommodates two carabiners. Self-lubricated brass bushings are perfect for light applications at low speed. Prusik knots can be installed on either side (aramid cord suggested) making it an ideal pulley for rigging a hauling system on route or managing crevasse rescues.
