Overview

Lead dinghy or catamaran lines, or manage control lines on a larger yacht, with the Ronstan Series 30 Utility single block. Its two-stage ball bearing system reduces friction across the working load range, while the swivel shackle head provides alignment options.

Key features

  • Two-stage bearings maintain consistent operation as the working load changes.
  • High static and dynamic load capacity supports both steady and changing loads.
  • A shackle can be fitted in either of two planes to align the block with the line.
  • Lightweight construction keeps added rigging weight down.
  • UV-stabilized sheaves and cheeks suit exposure aboard.
