Tech-Kern™ is a Kernmantle 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 for your kernmantle rope requirements.

* Knots and abrupt bends significantly reduce the strength of all ropes and lowers the maximum working load.
** For situations where a person is NOT on the rope, the working load may be doubled.
