3M CT8BK50-C Cable Tie 8 Inches 50 Lb Black

Product Description

The 3M CT8BK50-C is a black nylon cable tie rated for 50 pounds of tensile strength at 8 inches in length. Cable ties in this class are used by electricians, HVAC technicians, and other tradespeople to bundle and secure wire harnesses, conduit runs, refrigerant line sets, and other grouped components. The black color provides UV resistance suitable for outdoor and exposed installations. The self-locking head engages on insertion and holds the bundle securely without tools beyond basic installation.

This cable tie is appropriate for residential and light commercial installations where a reliable, general-purpose bundling solution is needed. Typical applications include securing wire harnesses inside electrical panels or control boxes, bundling refrigerant line insulation, organizing low-voltage wiring runs in HVAC systems, and managing cable bundles in exposed outdoor locations where UV degradation is a concern.

Installation Notes

Cable ties of this type are installed by hand or with a standard cable tie installation gun that controls tension and trims the tail flush. Always power down or de-energize circuits before working inside electrical enclosures or control panels. Trim the tail close to the locking head to avoid sharp edges that could damage wire insulation or create a safety hazard. Follow applicable NEC guidelines when bundling conductors inside enclosures.
