The Prusik Loops are sewn as a continuous loop. Our heavy-duty stitching uses a thread that is 150% thicker/ stronger than other brands. Since not all PMPs are equally sized, we have created 2 sizes of Short Prusiks to work with the Long Prusiks. The stitches are covered with a transparent shrink. Testing shows that a single RescueTECH Sewn Prusik pulled on RescueTECHs ACCESS 1/2 Lifeline starts clutching/slippin” at a strength of 3,000 lbf*. When pulled end-to-end the single loop strength exceeds 4,500 lbs. Marked with durable labeling to help product identification.

* Results may vary depending upon brand and condition/age of the main line
