Features: Reinforced nylon with high pressure and tensile load, good toughness, high elasticity and abrasion resistance. Flame retardant, it has a stable performance even in a high temperature circumstance. Chain shape like chain link by a large number of units composed of freely rotating between links. They reduce wear and stress on cables and hoses, prevent entanglement, and improve operator safety. Widely used to surround and guide flexible electrical cables and small hydraulic or pneumatic hoses connected to moving automated machinery.
