Featuring a low friction 2-stage ball bearing system, this block ensures smooth operation and consistent performance across the entire load range. Its high static and dynamic load capacities make it suitable for demanding environments, providing strength and durability without adding unnecessary weight. The versatile head fittings allow for easy integration into various rigging configurations, making it an adaptable choice for marine and other lifting applications. The sheaves are made to run on Acetal or Torlon ball bearings, which offer high performance and longevity, reducing wear and maintenance over time. With a 30mm (1-3\/16 inch) sheave diameter and an maximum rope capacity of 8mm (5\/16 inch), this block is designed to handle significant loads while maintaining smooth operation. The maximum working load limit is 660 pounds, with a breaking load of 1,650 pounds, providing a robust safety margin for demanding tasks. Weighing only 1 ounce, the Ronstan Series 30 is lightweight and easy to handle, making it ideal for boats and other mobile rigging setups.
