PETZL Tandem Pulley

The PETZL Tandem is a double pulley designed for movement along textile rope, used for Tyrolean traverses and rope-transport applications. It is intended for professional and recreational rope work and is not suitable for steel cable.

Main features

• Double fixed-side pulley configuration to guide two ropes or reduce friction on a traverse.
• Aluminium side plates and sheaves for low weight and corrosion resistance.
• Specifically designed for rope use — not for steel cable.
• Attachment hole accepts up to three carabiners for flexible rigging options.
• Sheaves mounted on bearings to provide high efficiency under load.

Typical use includes Tyrolean traverses, rope haul systems and technical rope transfer during work-at-height or rescue operations. Use with ropes up to 13 mm in diameter according to manufacturer specifications.
