Petzl Spin L1D Double Pulley

When hauling heavy loads or building complex mechanical advantage systems, friction is the enemy. The Petzl Spin L1D tackles this head-on with sealed ball bearings and a 95% efficiency rating, letting you lift more with less effort.

Who is it for

Rope access technicians, rescue professionals, and arborists who need a reliable, high-efficiency double pulley for work at height, hauling, and technical rescue scenarios.

Main features

• Double pulley with two stainless steel sheaves mounted on sealed ball bearings for minimal friction.
• Accepts ropes from 7 to 13 mm in diameter, covering most work and rescue ropes.
• Pivoting side plates allow quick installation on the rope without disconnecting the device.
• Large attachment point accommodates multiple carabiners, ideal for complex systems.
• Aluminum side plates keep weight low while maintaining strength.
