    Yale Kernmaster Orange and Blue 11mm Climbing Rope

    As low as$1.45
    Yale Kernmaster 11mm is a static-rappelling line constructed with a traditional “mantle” sleeve consisting of 48 strands of polyester. The inside, or “kern,” is a braided core of energy-absorbing nylon. The core is fully steam-stabilized to enhance the rope’s flexibility and prevent hardening in service. The braid also bends more easily and with less fatiguing of the core when cycled over sheaves.

    Solid Static Line

    I tried climbing on Yale Kernmaster for awhile, thinking the thicker rope would give my hands a break from the narrower lines I'd been using. It worked, but it felt heavy, so I went back to other options. It has REALLY shone, however, as a tree pulling line. I've pulled insane back leans over with this line, and it still looks fantastic. The low-stretch kept me from wasting energy stretching out the rope before the tree starts to move, and has been an invaluable 200' hank for several years now.
