 | Prusik Loop Material Guide Prusik loop material should be approximately 60% to 80% of the standing line diameter. If the hitch is too small, the hitch will be tight, making it difficult to free and then move the loop. If the diameter is too large, the hitch will not tighten up enough to grip and will slip. Flexibility is important. A cord that is too stiff will not allow the hitch to tighten enough to grip the standing line. In life safety applications such as rescue and belays, many authorities recommend the use of two tandem triple wrap Prusik hitches. Many authorities suggest using 8mm cord for 1/2" rope and 7mm cord for 7/16" ropes.
It is ultimately your responsibility to determine, select and use accessory cord and rope combinations that will work reliably in any life supporting situation, taking into account your experience, level of training and environmental conditions. |
