This pre tied Prusik loop is made from 8mm Donaghys Armor Prus cord with a metal floating thimble. The loop has a finished length of 700mm and is made from 2000mm of cord. It is suitable for a range of rope climbing applications.??The loop is tied with double fishermans joining knots and the cord ends have been sealed with tape.??The thimble reduces wear on the cord and improves its strength due to a greater bend radius. The cord can be rotated through the thimble so you can still vary the friction hitch location.
