Yale Blue Moon 11.7mm Climbing Rope – XTC-24 Competition Arborist Line
The Yale Blue Moon 11.7mm is an innovative lightweight 24-carrier arborist climbing rope designed for peak performance in both MRS (Moving Rope System) and SRS/SRT climbing systems when paired with compatible hardware.
Built with Yale’s exclusive 24-strand Tite-Braid™ cover, Blue Moon virtually eliminates cover milking while maintaining a smooth, consistent surface that performs exceptionally well with mechanical ascenders and hitch tending systems. Its braided-filament polyester core delivers a firm rope structure that resists work hardening and provides long service life.
Pro Tip: Blue Moon’s true 11.7mm diameter gives climbers the lightweight handling of an 11mm rope with the fuller hand feel of a traditional 1/2″ climbing line — making it one of the most versatile ropes in its class. Specifications
