7.6x550mm Heavy-Duty Nylon Cable Tie (UL & TSCA Approved)
The 7.6x550mm nylon cable ties are extra-long self-locking fasteners engineered for bundling large cable groups that cannot be secured with standard-length ties. Featuring a 550mm (21.6") strap length, 7.6mm width, and 120 lbs tensile strength, they provide a reliable, heavy-duty fastening solution for wire bundles, cable harnesses, and industrial equipment wiring.
Manufactured by Wuhan MZ Electronic from UL-approved Nylon 66, these long zip ties combine superior mechanical strength with excellent electrical insulation and resistance to heat, aging, and corrosion. With a bundle diameter capacity ranging from 4mm to 160mm, they allow efficient binding around wide or bulky cable arrangements without requiring separate buckles.
Ideal for industrial cable management, electrical installations, power distribution, telecommunications, and automotive wiring harnesses. Available in standard Natural and UV Black, with custom colors available for OEM orders.
