  • Two-stage ball bearings help the sheave turn with low friction under varying loads.
  • Capacity for both static and dynamic loads supports loaded line handling.
  • A weight of 3.4 ounces keeps the block light.

  • UV-stabilized sheave material and impact- and UV-resistant cheeks suit exposure on board.
