Self-lubricated brass bushings are perfect for light applications at low speed. Unlike other pulleys with fixed side plates, the Sphinx allows for a prusik knot to be installed on one side (aramid cord suggested) making it ideal for rigging a haul system on route or managing crevasse rescues.__WEIGHT: 93g (3.3oz)_ Max Breaking Load: 24kN, 5396 LBF_ Working Load Limit: 2kN x 2 = 4kN, 450 LBF x 2 = 900 LBF
