3M CT4BK18-C Cable Tie 4 Inch 18 Lb Black

Product Description

The 3M CT4BK18-C is a 4-inch black cable tie rated to 18 pounds tensile strength. Designed for bundling and securing wire and cable runs, this tie provides a reliable, low-profile fastening solution in electrical, HVAC, and general trade applications. The black color offers UV resistance suitable for both indoor and outdoor installations. Installers reach for this size when organizing low-voltage wiring, control wiring bundles, or small conduit groups where a compact, strong tie is needed.

This cable tie is appropriate for residential and light commercial applications. Electricians, HVAC technicians, and control panel builders commonly use 4-inch ties for wire management inside enclosures, air handlers, and equipment cabinets. The 18-pound tensile strength rating is suitable for small to medium wire bundles where a secure, flush-cut finish is required.

Key Features

• 4-inch length for compact bundling applications
• 18-pound tensile strength for reliable wire bundle retention
• Black color for UV resistance in indoor and outdoor environments
• Self-locking design for quick, tool-free installation
• Flush-cut tail after cinching for a clean, low-profile finish

Compatibility

Designed as a general-purpose cable tie for use in electrical, HVAC, plumbing, and control wiring installations where a 4-inch, 18-pound rated tie is specified.

Installation Notes

Cable ties are installed by hand or with a cable tie gun; no special tools or power shutoff is required for the tie itself, though all wiring work must comply with applicable NEC requirements. Cinch the tie snugly without overtightening on delicate insulation. Trim the excess tail flush with flush-cut pliers or a cable tie installation tool to eliminate sharp edges that could damage adjacent wiring or injure technicians during service.
