Pastic Cable Ties 7x300mm Black

Pastic Cable Ties 7x300mm Black are the widest and longest ties in the Pastic range. They are made from nylon. SKU: Cable-Ties-7x300mm-Black.

What the numbers mean

• 7mm wide: the broadest strap in the range, so it spreads the grip across a heavy bundle.
• 300mm long (30cm): the longest in the range, giving room to go round a thick bundle.
• Nylon: the material for the whole tie.

Where this size is used

These ties are meant for heavy bundles, cable tray and basket work, and thick multi-core runs on commercial installations.

• Cable tray: an open shelf that carries cables along a wall or ceiling.
• Basket: the same idea, built from wire mesh.
• Multi-core cable: several separate wires inside one outer sheath.

Check before you order

Measure the finished bundle, not the loose cables. The tie must wrap all the way round and still leave tail to feed back through the head. A bundle that is far smaller than 300mm allows will leave a lot of tail to trim, so a shorter tie from the range may be the better fit.

On a job with mixed cable sizes, use this tie for the thick trunk runs and smaller ties for the individual drops.
