Petzl SPIN L1D – High-Efficiency Pulley with One-Way Rotation

Petzl SPIN L1D is a professional high-efficiency single pulley with an integrated swivel, designed for work at height and technical rescue systems. It is particularly suitable for use in conjunction with a descender when setting up heavy-load deviations and hauling systems.

The distinctive feature of the SPIN L1D is its one-way faceted sheave. It provides high efficiency when hauling while creating additional rope friction for increased braking when lowering heavy loads.

Rope Installation While Connected to the Anchor

The SPIN L1D features an opening moving side plate with a triple-action opening mechanism. The system is quick and easy to operate, even while wearing gloves.

The rope can be installed while the pulley remains connected to the anchor, simplifying installation and manipulation in professional rope systems.

93% Hauling Efficiency

The 40 mm sheave is mounted on sealed ball bearings and provides an efficiency of 93% when hauling.

The faceted sheave rotates in only one direction. During lowering, its design creates additional friction zones for the rope, providing additional braking when controlling heavy loads.

Integrated Swivel

The integrated swivel allows the pulley to orient itself according to the direction of the load, even while under tension. This simplifies handling and helps maintain efficient system alignment.

The swivel attachment point accepts up to three carabiners and also allows ropes or slings to be connected directly for easier manoeuvres.

Compatible with a Prusik Friction Hitch

The special side plate design protects the rope path and allows the use of a Prusik friction hitch in a progress-capture hauling system.

Visual Safety Indicator

A red indicator provides a clear visual warning when the moving side plate is unlocked, allowing the user to quickly verify the device before loading the system.
