The STERLING TRIAD 11.9 mm arborist climbing rope is designed for smooth operation with mechanical devices and friction hitch systems. It combines kernmantle characteristics with double braid flexibility, resulting in a stable, round profile with excellent handling.

The hybrid core construction, consisting of multiple twisted inner nylon cores and a braided outer core, works together with a 32-strand polyester sheath. This balanced design ensures consistent load distribution and reliable performance in devices.

Low elongation optimized for SRS provides efficient ascents, while maintaining versatility for MRS. The low-friction sheath enables smooth movement through mechanical devices and cordage-based systems.
