Armbury Gamut 11.5 mm Arborist Climbing Rope

Armbury Gamut 11.5 mm Arborist Climbing Rope

Armbury Gamut is a lightweight 11.5 mm arborist climbing rope designed for use with modern mechanical devices. Its 24-strand double-braid construction combines a polyester sheath and polyamide core for flexibility and knotability, helping it run smoothly through hardware and feel manageable when footlocking.

Built for work in the canopy

When your route calls for repeated movement through the tree, Gamut’s supple handling helps you manage the line and tie knots without unnecessary bulk. A tight eye-spliced termination is available for setups that call for a compact connection.
