Product Details

This is the lightweight rescue pulley you've been waiting for. The SMC CRx 1" Pulley is incredibly strong, yet weighs a mere 1.8 ounces.
  • Easier to carry in your life jacket pocket or swiftwater rescue kit than other, heavier pulleys.
  • The pulley works great in Z-drag 3-to-1 extraction systems, rated at an amazing 22kN (4,946 lbf) load strength.
  • High-strength aluminum sides keep it light while a stainless steel axle resists corrosion.
  • Also features a durable and smooth-running Delrin® sheave.
  • Handles ropes up to 1/2" (13 mm) in diameter.
  • This pulley has the required prusik-minding capability for use in 3-to-1 mechanical advantage systems, making it easier to haul or lower heavy loads.
