Double Braid



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.

Technora® has a high melting point and acts as a heat sink when used with high-friction applications, as with descent devices. If heat is on your mind, consider Tech-Kern.

* Knots and abrupt bends significantly reduce the strength of all ropes and lower the maximum working load.
** For situations where a person is NOT on the rope, the working load may be doubled (5:1).
