Our Double Pulley (Tandem Block Roller – Dural) is a high-performance lifting and rope-crossing device designed for smooth and controlled movement on inclined rope systems. Built with lightweight yet strong dural construction, both the side plates (cheeks) and rollers ensure durability without adding unnecessary weight.

This pulley features two consecutive rollers that provide enhanced stability and smoother travel, making it ideal for rope crossings, adventure parks, zip line setups with small inclinations, and mechanical advantage systems.

Equipped with ball bearings, it delivers efficient rope movement with minimal friction. It is compatible with ropes up to 13mm diameter and supports demanding load applications while maintaining reliable performance.

⚠️ Important:

• Maximum operating speed: 10 m/s

• Not suitable for steel cables

• Exceeding speed limits may damage the rollers

This trusted double pulley is perfect for rope parks, rescue setups, hauling systems, and professional adventure installations requiring strength, smooth performance, and long-term reliability.
