3M CT6BK40-C Cable Tie 6 Inch 40 Lb Black

Product Description

The 3M CT6BK40-C is a black nylon cable tie rated for 40 pounds of tensile strength with a 6-inch length. Cable ties in this class are standard hardware for bundling wire harnesses, securing conduit runs, organizing low-voltage control wiring, and managing refrigerant line insulation in HVAC, electrical, and plumbing installations. The black coloring indicates UV-stabilized nylon construction, making this tie suitable for both indoor panels and outdoor or exposed applications where sunlight resistance matters. HVAC technicians, electricians, and plumbers reach for ties like these on nearly every service call.

This cable tie is appropriate for residential and light commercial applications. Common uses include bundling thermostat wiring, securing refrigerant line sets to hangers, organizing electrical panel wiring, and managing low-voltage control cable in mechanical rooms. The 6-inch length and 40-pound tensile rating suit a wide range of bundle diameters encountered in typical trade work.

Installation Notes

Cable ties of this type are installed by electricians, HVAC technicians, and plumbers as part of standard wiring and securing tasks. Always power down circuits before bundling or rerouting electrical conductors. Ties should not be overtightened on insulated conductors in a way that deforms the insulation. Follow NEC and local code guidelines for wire management and support spacing.
