Kernmaster is a static-rappelling line constructed with a traditional "mantle" sleeve consisting of 48 strands of polyester. The inside, 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. The sleeve is either white with red tracers or solution-cast fiber (color added prior to yarn production), which makes for lasting colors and enhanced wear resistance.

Ideal for static rappelling applications in many industries.
Kernmaster has good energy absorption and performs more like a 24-strand than other kernmantles, allowing for both access and DdRT climbing.
|Diameter (Inches)||Average Break Strength *(Lbs)||Minimum Spliced Break Strength *(Lbs)||Maximum Working Load 10:1 **(Lbs)||Weight (Lbs/100f)|
* 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).
Green working 155 ft. lbs./lb.
Red ultimate 9,775 ft. lbs./lb.
Specific Gravity: 1.23
Dielectric Strength: The maximum allowable leakage for clean, dry Kernmaster is 500 micro- amperes when tested at 100kV per Yale Method 712-1701 Rev 1 "Routine Production Test." Absorbed and entrained moisture or impurities will increase rope’s conductivity dramatically.
