Our Bulldog Prusiks with synthetic Technora materials are designed with extreme resistance to both abrasion and heat. These prusik cords and lanyards are ultra-reliable and durable. While they were designed to make sliding on arborist ropes easier, they can also be used for rappelling in applications with most other ropes. This prusik loop allows you to modify the hitch with any number of different knots applied. It is engineered specifically to provide a perfect grip and offer incredible abrasion resistance. The synthetic Technora materials offer exceptional stability and a remarkably high melting point. With an eye sewn by experts at Pelican Rope, these prusiks are designed to survive longer in some of the most extreme conditions. 8mm option is 100% pure technora. The 10mm option is a technora cover with nylon core. Prusik Loops Are Ideal For: Arborists, Rappelling, Rescue Loop Applications, Tree Friction Savers.
