  • Halyard, vang, and backstay applications on boats up to 9m (30ft).
  • Control line applications on larger yachts.
With their high-strength grade 2205 stainless steel sheave & hub and triple bearing race, the High Load versions are designed to handle high dynamic or static loads, making them an excellent choice for demanding situations.
