A pulley with self-lubricating bushings & a rope clamp/grab "all in one". A new concept in pulleys with an anti-return feature. The Mini Traxion can be used for sack-hauling, but it can also be used for the attatchment of a person. Great for setting up hauling systems, for back-up belaying & for moving along a tyrolean traverse, where the cam operates as an anti-return device. Weight 165g
