Nylon construction This heavy-duty pulley block is built from nylon to withstand harsh marine conditions while minimizing friction for smooth operation. High working load capacity Designed to support a working load limit of 460 kg, making it suitable for demanding applications and improving performance on the water. Rope compatibility Accommodates rope diameters up to 10 mm and is compatible with a range of rope types, making it a versatile choice for both sailing and industrial needs. Advanced bearing system Features an innovative bearing system that allows the pulley to rotate smoothly, reduces wear, and improves operating efficiency during use. Use scenarios - Sailing and rigging: halyards, topping lifts, and other deck lines where reliable performance and smooth movement are important. - Industrial and dockside tasks: rigging and lifting on ships or in workshops that require a robust nylon block with high load capacity. - General purpose on boats and equipment: suitable for diverse line handling where corrosion resistance and consistent performance are desired.
