Yale Phantom 11 mm 80 m Climbing Line comes in a 80-metre pre-cut length, providing extra rope for very tall trees, large spreading canopies, and SRS systems requiring multiple redirects. Based on Yale’s popular Kernmaster construction, Phantom uses a 48-strand polyester cover with a polyester core to reduce elongation to about 1.5% at 10% of MBS, delivering a super-static feel with minimal energy lost to rope bounce. The smooth jacket runs efficiently through ascenders and mechanical climbing devices, while the distinctive sheath pattern provides excellent visibility in the canopy. A red core distinguishes Phantom from nylon-core Kernmaster lines and provides a useful inspection indicator—if the red core becomes visible through the jacket, the rope requires immediate attention. Yale Phantom is intended for professional arborists wanting a low-stretch SRS climbing line and accepts sewn-eye terminations only.
