6mm & 8mm  

Prusik cords help reduce friction and improve the safety of your climb. When this small stretch of cord is tied correctly, it can auto lock under load, which provides you with additional protection. You need a specific size of prusik cord based on the size of your climbing rope. 

At Northern Arb, we have durable 6mmm and 8mm prusik cords for thinner climbing ropes. Make sure the prusik cord 60% to 80% the size of your climbing rope for the best results.
