Overview

Route dinghy and catamaran primary leads or larger-yacht control lines through the Ronstan Series 30 single loop-top block. Its two-stage ball bearing system reduces friction across the working load range, while the lightweight construction keeps the block at 28 grams.

Key features

  • A shackle can be fitted in either of two planes to align the block with the line.
  • UV-stabilized sheave and cheek materials provide resistance to ultraviolet exposure.
  • Impact-modified, fiber-reinforced nylon cheeks support a lightweight assembly.
  • Grade 316 stainless steel forms the load straps and head fittings.
