The STERLING TRIAD 11.9 mm arborist climbing rope with spliced eye is designed for smooth operation with mechanical devices and friction hitch systems, enhanced with a low-profile spliced eye (EV splice) for efficient system setup.

The rope combines kernmantle characteristics with double braid flexibility. Its hybrid core construction—made of multiple twisted inner nylon cores and a braided outer core—works together with a 32-strand polyester sheath to deliver a stable, round profile and consistent handling.

Low elongation optimized for SRS ensures efficient ascents, while maintaining full usability in MRS systems. The low-friction sheath allows smooth movement through mechanical devices and cordage-based systems.

The low-profile splice (EV splice) passes easily through friction savers and compatible mechanical devices (non mid-line attachable), enabling fast and clean rope integration without knots.
