Kernmantles

Static-rappelling Kernmaster™ line is constructed with a traditional "mantle" sleeve consisting of 48 strands of polyester. The i.nside, 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 or dropped over a parapet.

Tech-Kern is a Kernmantle style rope consisting of a braided Technora Aramid core covered by a 48-strand Technora mantle. If you are familiar with our Kernmaster you already know the advantages of a braided core rappelling line. The Tech-Kern was designed to bring the highest heat resistance to the market as Technora has a high melt point and acts as a heat sink when used in frictional applications as with descent devices. If heat is on your mind consider Tech-Kern.
