70 meter pre-cut hank, 11 mm SRT super-static climbing line. Yale Phantom 11mm is the all-polyester version of the popular Kernmaster series of climbing lines. The polyester core offers minimal elongation on the ascent (1.5% elongation at 10%), essential for SRS climbing. In addition, the smooth jacket works flawlessly with ascenders and mechanical devices. The Yale Phantom core is red to help distinguish it from the nylon-core Kernmasters, and the colour also aids in outer jacket inspection (if you can see the red through the jacket, you have a problem!). Finally, the unique sheath pattern ensures you can spot this rope a mile away—ideal for single rope technique, sewn eyes (terminations) only.
