PETZL Spin L1 – Very High Efficiency Single Pulley with Swivel

Designed for maximum simplicity and exceptional efficiency: The Petzl Spin L1 is a single pulley that combines a large diameter sheave mounted on sealed ball bearings with a swivel feature, making it ideal for hauling, load deviation systems, and tyroleans in work at height, rescue operations, and tree care.

Key Features

• Openable while attached to anchor: The pulley can be quickly and easily opened thanks to triple-action side plate unlocking, even when connected to the anchor and while wearing gloves.
• Visual safety indicator: A red mark alerts users if the moving side plate is not properly locked.
• Rope protection: Specially designed side plates safeguard the rope path, extending rope life and maintaining system safety.
• Exceptional efficiency: Large 38 mm diameter sheave running on sealed ball bearings ensures 95% efficiency.
• Swivel function: Allows the pulley to orient under load, accepts up to three carabiners, and permits direct connection of ropes or slings to facilitate rigging and maneuverability.
