This little kit packs a big punch. Designed for glacier travel, this 4:1 pulley system allows for quick self-rescue or rescue of another person in the event of a fall into a crevasse. The Pico Double Pulleys weigh only 3.3 oz. each and are rated for 30kN. When mated with our 6mm TRC cord and unique 5mm TRC Prusik, this kit provides a super compact mechanical advantage setup.
