Strong nylon construction: Made from high-strength nylon, this pulley block is built to resist harsh marine environments and minimize friction during operation. 460 kg load rating: With a maximum working load of 460 kg, it delivers reliable performance under heavy use. Accepts up to 10 mm line: Designed to accommodate lines up to 10 mm in diameter, suitable for a variety of rope types in sailing and industrial applications. Efficient rotation mechanism: An advanced bearing system provides smooth rotation, improves efficiency and reduces wear. Applications: - Sailing and rigging: ideal for halyards and control lines on boats where smooth operation and high load handling are valuable. - Industrial rigging: suitable for lifting or tensioning heavy lines up to 10 mm in shipyards or workshops. - Deck hardware and marina installations: durable, low-friction line handling in dockside setups.
