Petzl Nano Traxion Pulley

A pulley that allows rope to pass in one direction and locks in the other. That is progress capture, and it is what makes this micro-pulley useful far beyond climbing.

What it is for

Primarily for hauling systems, directional redirects, and climbing applications. Its progress capture also makes it a common choice for rescue and tactical use.

The cam

Machined, toothed steel. It bites into frozen or muddy ropes, where a smooth cam would slip—precisely the conditions where you need it to hold.

Efficiency

Integrated high-efficiency bearings. In a hauling system, pulley efficiency pays off directly in effort with every pull.

Compatibility

7 to 11 mm ropes.

Personal protective equipment. Its use requires appropriate training and regular inspection according to the manufacturer's instructions.
