Durable double-roller pulley set (2 × M50) made from 304 stainless steel for reliable indoor and outdoor use Key benefits Built to last: 304 stainless steel construction resists rust and corrosion so the pulleys perform reliably in wet or humid environments and require minimal maintenance. Smooth, tangle-free operation: the double traversing rollers guide rope cleanly through the block to prevent swaying, knotting, or clogging during use. Full rotation for alignment: a rotating ring on top provides 360° swivel so the pulley self-aligns under load and reduces rope twisting. Labor saving: designed to reduce effort when lifting or moving loads; the included double bottle pulleys distribute load across two sheaves to make hoisting easier and more efficient. Ready for rope use: compatible with standard ropes and cords for domestic, workshop, and light industrial tasks. Features and specifications Material: reliable 304 stainless steel — corrosion resistant for indoor and outdoor applications. Design: double roller block with smooth-running traversing rollers and a top rotating ring offering 360° swivel. Package: 2 × M50 double bottle pulleys. Function: guides and redirects rope for lifting, pulling, or traversing without excessive sway or jamming. Typical applications Home and garden: install as a durable washing line pulley for outdoor clothes drying where weather resistance is important. Workshop and garage: use for hoisting tools, lumber, or equipment into loft storage or for light material handling tasks. Small industrial or DIY projects: assist with lifting, rigging, or repositioning components where a compact, corrosion-resistant double pulley is needed. Practical notes Attach through the top rotating ring to a compatible hook, shackle, or suspension point that matches your load requirements. Designed to work with rope; select rope type and diameter appropriate for M50 sheave size and the load you intend to move. For critical lifting or certified load-bearing requirements, use this pulley as part of a system that meets applicable safety standards and load ratings. What makes it stand out Combination of 304 stainless steel durability, smooth traversing rollers, and a full 360° swivel ring delivers reliable, tangle-free performance for a wide range of rope-based lifting and hauling tasks. Supplied as a pair (2 M50 double bottle pulleys) to enable simple block-and-tackle setups or to replace worn pulleys quickly.
