Lead blocks are a low profile solution for leading halyards or other rig sail controls back to cleats or jammers.
Precision moulded 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.
