Tree Line

Tree Line is a purpose-built climbing and work-positioning rope engineered for high-performance use as a hitch cord in professional arborist climbing systems. Constructed with a 32-carrier, 1-ply braided sleeve, Tree Line delivers an exceptional balance of hand feel, abrasion resistance, and predictable performance across a wide range of climbing systems. The sheath features a carefully balanced Technora-to-polyester ratio of nearly 1:1, giving the rope the heat resistance, grip, and structural stability of Technora while retaining the smooth handling and flexibility that polyester is known for.

At the center of Tree Line is a 12-strand core built from a twisted blend of HMPE and Vectran fibers—a design that brings together the 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 in demanding environments.

Key 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.

Tree Line Specifications and Data


* Average break strength is based on spliced rope or capstans samples. Knots and abrupt bends significantly reduce the strength of all ropes and lower the design factor.
** Suggested design factor is based on static or moderately dynamic lifting/pulling operations. Instantaneous changes in load, up or down, in excess of 10% of the rope’s suggested design factor constitute hazardous shock load and would void the suggested design factor recommendation. The end user is responsible for choosing the correct design factor specific to their application.
