The Petzl Pro Traxion is basically a heavy duty version of the Pro Traxion. This makes it ideal for use as a big wall hauling device as it is more efficient (~20% more so than a Mini-Traxion) due to the use of sealed ball bearings.
If you are after an all in one hauling device for a big wall trip this is the one to go for.
Should only be used with an oval krab such as a Petzl 'OK'.
Suitable for ropes: 8-13mm
Weight: 265g
