BRAID ON BRAID

A BRAIDED CORE WITH A BRAIDED SHEATH.

Strength & durability

  • Strong, durable, with high abrasion resistance.
  • Ability to retain its shape under rigorous conditions.
  • Balanced twists prevent kinking.
  • Inner core bears load while protected by the outer layer known as the sheath.
NBI Specialised True Kernmantle High-Access Rope
  • Lower abrasion resistance, not as strong or durable.
  • The lack of balance leaves the rope susceptible to kinks and twists.
  • Vulnerable to unravelling if core cut.
  • Both core and sheath contribute to strength.

Uses

Used in high-access climbing, repelling, caving, rescue operations, suitable for safety applications.

Commonly used in marine and general purpose applications, not suitable for safety-critical applications.

Safety aspect

In True Kernmantle rope, the presence of multiple cores provides enhanced safety and peace of mind in case of damage.

Even if only one core of the kern remains intact, the rope retains the capacity to support two individuals, ensuring safety even in scenarios where both the sheath and multiple inner cores are compromised.

Any cut which damages the core compromises the rope’s structural integrity, causing the braid to unravel.
