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 fac- tional applications as with descent devices. If heat is on your mind consider Tech-Kern. Average Spliced Break Strength* Minimum Spliced Break Strength* * Knots and abrupt bends significantly reduce the strength of all ropes and lowers the maximum working load. Specific Gravity: 1.4 ** For situations where a person is NOT on the rope, the working load may be doubled.
