About this item

  • GM CLIMBING 8mm Prusik Loop, available in lengths of 18" and 24", yielding an MBS of 24kN /5400Lbs, and made of 100% high tenacity Polyester with CNC machine stitchings at joints. Used to tie friction hitches on the standing line of 11~12.5mm (7/16~1/2inch), such as prusik knot, autoblock, and Klemheist knot in mountaineering, climbing, canyoneering, caving, rope rescue, tree care by the arborist, rigging aerial hammock, lifting, and etc.
  • Supple in handling, and double-braid constructed to be solidly round, it's easy to tie, dress and untie hitch knots (Prusik, Autoblock, Klemheist, etc) with this Prusik loop. When hitches around the rope, to have a good grip, the recommended diameter range of the standing line is 11~12.5mm / 7/16~1/2 inch.
  • 24kN High Breaking Strength allows the Prusik loop to expand its areas from professional to general uses. CNC machine stitching of sewn joints keeps the loop neat and free from traditional bulky knots, whilst still withstanding high strengths; A heavy transparent heat shrink sleeve is applied around the stitching to protect it from abrading during use and allow you to easily inspect the stitching condition. That has the Prusik loop gain unbeatable durability and longer service life.
  • Made of High Tenacity Polyester to increase performance in various aspects, to get higher tensile strength and excellent abrasion resistance. Low water absorption makes the Prusik loop highly adaptive to outdoor activities. Double braid - Core and Sheath rope construction - this “sturdy sheath” further enhances great abrasion resistance and guarantees long-life utilization.
  • One of the most versatile gears added to your rack, compact and light, easy for carrying, convenient for a wide variety of uses, from ascending ropes, rappel or abseil backup, making tandem prusik belay in rescue, adjustable anchor set-up, to general recreational sports and activities, like rigging aerial yoga silk, hanging tarps and hammocks.

PRUSIK
prusik

How to choose Prusik diameter?

  • In most cases, the Prusik cord should be about 60% to 80% of the standing line (main rope) in diameter.
  • Skinnier cords will have a too-tight bite, Thicker cords in opposite can't generate enough grip on the standing line and tends to slip.
  • For safety, always take tests of the Prusik knot to slide and re-grab on the rope in safe places prior to using it at height.

Tough & affordable loop, but further testing needed.
4 Stars
Tough & affordable loop, but further testing needed.
Tested 2 after 6 months of use and they sheered at the stitching at 17.7kN & 17.4kN. These loops are rated at 20kN new. Both loops were bought at the same time. I'm going to buy a couple more and test them fresh out of the package and see what results I get and whether the 20kN rating stands up.Testing done with a Rock Exotica Enforcer and a ~98:1 manual haul system.
