The Petzl Micro Traxion is a compact and lightweight progress caputre pulley designed for crevasse rescue, hauling, and self-secue, and for use as an emergency ascender.
The Micro Traxion is an ultra-light (85 g), ultra-compact progress-capture pulley that is exceptionally efficient (91%) thanks to its sealed ball bearings. The cam can be locked in open position so the device can be used as a simple pulley.
