The strength, flexibility and unsurpassed durability of kernmantle rope by Yale Cordage are due to the traditional “core jacket” (or kernmantel, in German) design. A braided core adds energy absorbing strength, while the outer mantle maintains the rope’s tensility, resilience and heat resistance. Ideal for static rappelling applications in many industries, Yale Cordage’s Kernmaster kernmantle rope offers a polyester mantle and a strong nylon core. Tech-Kern is an advanced kernmantle rope ideal if frictional heat (with use of decent devices) is a concern. A Technora Aramid core is enveloped in a 48 strand Technora mantle that offers the highest heat resistance on the market. Trust the cordage experts of Yale Cordage with your kernmantle rope requirements, whether standard or custom. For over 60 years, Yale Cordage has taken pride in its position at the forefront of synthetic fiber innovation and top quality cordage manufacturing.

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.
