Series 30 Utility Blocks feature stainless steel ball bearings and can be used in various rigging systems and applications, often used as primary lead blocks on dinghies and catamarans or control lines on larger yachts. Special Purpose sheave versions feature a Nylatron® sheave and are compatible for use with wire rope.
Lead blocks are a low-profile solution for leading halyards or other rig sail controls back to cleats or jammers. Precision molded Acetal sheaves running on Acetal or Torlon® ball bearings provide high performance & low friction. The 2-stage ball bearing system provides consistent performance over the full load range.
