ROPE LOGIC is offering an improved version of the popular Bee-Line. Made with Technora-black, these eye tails feature a para-aramid fiber with high tensile strength, high modulus and excellent resistance to heat and chemicals. It has been solution dyed which ensures the color reaches right to the core of each filament, giving it a deep black color and the added bonus of increased UV resistance. As a filament yarn, Technora has proven its superior properties in our climbing prusiks. It has a 100% Vectran fiber core, 75% black Technora cover, and 25% black filament polyester cover. The tensile strength is 10,350 lbs. (46 kN) working load limit is 1,035 lbs. (4.6 kN). Material: Nylon.
