Yale Treeline 8mm (5/16") Prusik Cord by the Foot

Yale tree Tree Line is high-performance hitch cord for the professional arborist. Tree Line delivers a great hand feel, abrasion resistance, and predictable performance. In this diameter, best suited for use on 11-12mm climbing ropes.

• Cord diameter: 8mm (5/16")
• Cord Tensile Strength: 7,000 lb
• Heat Resistant: Yes
• Construction: 50% Technora/50% Polyester cover, HMPE/Vectran core

The sheath is nearly 1:1 Technora-to-polyester. This gives the heat-resistance, grip, and structural stability of Technora while retaining the smooth handling and flexibility of polyester.

The core of Tree Line is a 12-strand, twisted blend of HMPE and Vectran fibers. This the combines high strength and low elongation characteristics of HMPE, with the exceptional creep resistance and thermal stability of Vectran. This hybrid core delivers dependable strength under load, controlled stretch for precise movement, and long-term stability even.

Features

• Advanced Fiber Construction: Built with a 32-carrier Technora/polyester braided cover paired with a twisted HMPE/Vectran core, delivering a strong balance of durability, heat resistance, and stability.
• Heat-Resistant Performance: The Technora-rich sheath offers exceptional protection against glazing and thermal buildup during repeated hitch cycles and sustained descents.
• Low-Stretch Core: HMPE and Vectran fibers provide controlled elongation, firm support under load, and long-term dimensional stability in demanding climbing environments.
• Smooth System Compatibility: Provides consistent friction behavior across climbing devices, friction savers, and redirects for controlled movement aloft.
