PMI® is proud to offer the latest innovation in accessory cords. Precision sewn loops form a sleek, low profile connection that is stronger than a knot. Clear tubing protects the stitches yet allows for easy inspection. Loops are built for those who are looking for a no-Knot solution for prusik minding pulleys. These Pre-Sewn prusiks work great in hauling systems that require a prusik load capture, the sewn prusik is always stronger and more reliable that a tied knot prusik.
