Overview

Set up dinghy control lines with the Ronstan Series 20 triple ball bearing block with becket and 2-axis shackle head. It provides low-friction line handling for vangs, Cunninghams and traveller controls, with a head that can be fixed in either of two orientations.

Key features

  • Ball bearing sheaves reduce friction as control lines move through the block.
  • A head that fixes at 0° or 90° gives you two alignment options.
  • Lightweight construction keeps the block's weight to 64g.
  • UV-stabilized sheaves and impact- and UV-resistant cheeks suit exposure on deck.
