Years of development, testing and fine tuning has made our Prusik cord a preferred choice by rescue schools, agencies and rescuers alike. Our sewn Prusiks offer unmatched performance—with strength equivalent to a tied Prusik loop, just without the cumbersome knot. The factory-sewn SecureStitchTM is covered with durable clear shrink tubing that allows regular inspection and helps protect the stitching for longer life. Some rescuers prefer a bound-loop style Prusik for cinching the attachment bight around the carabiner to help snug the Prusik to the connector. Our AZ Bound-Loop Prusiks are identical to our Sewn Loop Prusiks except that the shrink tube captures both sides of the loop while allowing adjustment. Working-At-Height / Industrial Rope Access / Technical Rope Rescue Working at height requires reliable, quality equipment. The AZ Bound-Loop Prusiks can be used with confidence in work-at-height maneuvers for industrial rope access or technical rope rescue when used in accordance with the regulatory safety standards under which they fall. Always use life safety equipment and gear according to the regulatory safety standards for which it is classified and/or certified.
