Ronstan guide blocks are a compact solution for guiding halyards or other rigging controls to cleats or jammers. Precision-molded acetal sheaves, mounted on acetal or Torlon® ball bearings, provide high performance and low friction. The two-stage ball bearing system ensures consistent performance across the entire load range.
