Ecm Industries Llc 46-421UVB Black Cable Tie 21 in 50 Pack

Product Description

The ECM INDUSTRIES LLC 46-421UVB is a 21-inch black cable tie engineered for rugged environments that demand high tensile strength and the ability to secure large bundle diameters. Each tie is manufactured using one-piece, injection-molded nylon 6/6 construction, eliminating the risk of component failure from parts working loose or breaking off. The locking mechanism holds tight without stretching or sliding, and raised ridges on the bent tip deliver a secure, positive grip once cinched. At 175 lb tensile strength and 0.35 inches wide, these ties are built for demanding trade and industrial applications. Sold in bags of 50.

These cable ties are well suited for HVAC, electrical, plumbing, and general mechanical applications where robust bundling of wires, conduit, hoses, or tubing is required. The 21-inch length and 5.5-inch maximum bundle diameter make them appropriate for larger bundles commonly encountered in commercial and residential mechanical rooms, panel work, and equipment installations. The black color provides UV resistance appropriate for installations exposed to sunlight or harsh ambient conditions.

Compatibility

Designed as a general-purpose heavy-duty cable tie for use in HVAC, electrical, plumbing, pool, and industrial trade applications requiring a 21-inch tie with high tensile strength.

Installation Notes

Cable ties of this type are installed by electricians, HVAC technicians, plumbers, and mechanical contractors as part of standard wire and conduit management practices. No special tools are required beyond standard flush-cut side cutters for trimming excess tail after cinching. Always verify the selected tie length and tensile rating are appropriate for the bundle size and load before installation. Do not exceed the rated maximum bundle diameter of 5.5 inches.
