At 300mm in length and 4.8mm in width, these heavy-duty black cable ties are the go-to choice for trade professionals who regularly tackle larger bundling and securing tasks that smaller ties simply can't handle. Known in the trade as the 12-inch cable tie, this size is a firm favourite among electricians, heating engineers, plumbers, and industrial maintenance teams who need maximum reach combined with a robust strap that holds firm under real working loads. Supplied in a 100-pack, they represent outstanding value for high-volume users.
The 300mm length and 4.8mm strap width make these ties well suited to the bigger jobs — securing large cable looms in distribution boards and consumer units, strapping insulation around 42mm and 54mm copper pipework, bundling flexible conduit runs, managing multiple flow and return pipes together, and fastening components in plant rooms where a standard-length tie simply wouldn't reach. The wider strap spreads the clamping load effectively, reducing the risk of cutting into softer insulation materials or deforming flexible conduit under tension.
The self-locking ratchet mechanism delivers a strong, positive lock with high pull-through resistance, keeping these ties reliable in environments subject to vibration, thermal movement, and the mechanical stresses typical of busy boiler rooms, commercial plant installations, and industrial settings. Moulded from high-quality nylon 66, they offer excellent resistance to UV, moisture, oils, and light chemical exposure — holding their integrity in the damp, variable conditions common to loft spaces, plant rooms, and partially exposed external pipework runs.
The black finish delivers a neat, consistent appearance across installations and provides meaningfully better UV tolerance than natural white alternatives — a practical advantage wherever ties are used near roof lights, external walls, or in any location with regular sunlight exposure.
