STERLING TRIAD 11.9 mm is an arborist rope designed for smooth operation with mechanical devices and friction hitches. It combines the properties of kernmantle construction and double-braid ropes, achieving a highly round profile while retaining flexibility.

The hybrid core, consisting of multiple twisted inner nylon cores and a braided outer core, works together with a 32-strand polyester sheath. The result is balanced load distribution between the individual rope layers, a stable profile and consistent running in devices.

Low elongation optimized for SRS ensures efficient ascents, while the rope remains suitable for MRS as well. The low-friction sheath enables smooth passage through mechanical devices and friction systems.
