Heavy-duty nylon pulley block designed for reliable, low-friction performance in demanding marine and industrial environments. Key benefits Durable construction: strong nylon resists harsh marine conditions so the block remains serviceable in salt spray and wet use. Smooth, efficient operation: the integrated bearing system ensures low friction and smooth rotation, reducing line wear and making adjustments easier. High load capacity: 460 kg working load limit supports high-demand tasks without over-specifying hardware. Broad rope compatibility: accepts line diameters up to 10 mm, compatible with a wide range of sailing and utility ropes. Important specifications Material: strong nylon for corrosion resistance and long service life in wet environments Working load limit: 460 kg Maximum line diameter: 10 mm Rotation: bearing system for smooth, low-friction operation How this solves problems Reduces friction and line chafe so ropes last longer and require less effort to trim or lift. Withstands marine exposure so you avoid frequent replacements or corrosion-related failures. High working load capacity gives confidence for demanding tasks while the bearing keeps motion efficient. Practical uses Sailing: control halyards, sheets, outhauls or spinnaker lines on small to medium boats where low friction and corrosion resistance matter. Marine deck work: lead and redirect dock lines, anchor lines, or control lines on tenders and workboats. Light industrial or workshop rigging: guide and support lines for equipment positioning, hoisting small loads, or temporary rigging where a 460 kg WLL is sufficient. What makes it stand out A practical combination of strong nylon construction and a bearing-driven sheave for a balance of durability, smooth action, and compatibility with common rope sizes. Simple specification set (460 kg WLL, up to 10 mm line) makes it easy to match to tasks without overengineering. Materials and performance are focused on delivering dependable, low-friction operation for marine and industrial applications that require a compact, robust pulley block.
