XTC Fire is specifically designed for the demanding needs of arborists, embodying the same characteristics of XTC ropes Yale has made for the last two decades.  XTC is a tight braid consisting of 16 individual strands of polyester. A high twist core of torque balanced polyester keeps the construction firm and round, providing an extra measure of safety. XTC is an excellent choice for both climbing line and bull rope due to its non-snagging, abrasion-resistant construction and excellent energy absorption characteristics.
