SwiftDry 4mm Nylon Clothesline Line

Finally, a clothesline cord engineered to outlast everything else on the market — and purpose-built for SwiftDry clotheslines. Manufactured exclusively for SwiftDry, this 4mm diameter black nylon cord is the last clothesline cord you'll ever need to buy. After testing over 20 suppliers and trialling everything from PVC-coated wire to braided stainless steel, galvanised, zinc-coated, and single-to-multi-strand options, we kept running into the same problems: lines that rusted, kinked, snapped, or tangled within a season — often without warranty support. The "UV resistant" claims. The rewashing. We designed this cord to be the answer to all of it.At 4mm diameter, it's thicker and significantly stronger than standard clothesline wire and cord available elsewhere. It is similar to extremely heavy-duty fishing line — the break strain is exceptional, and unlike wire alternatives, it simply cannot corrode. Salt air, rain, harsh sun — none of it will degrade this cord. No rusting, no kinking, no sharp edges catching your washing, hands or hair, and no washing ending up in the mud after an unexpected snap.UV-stabilised for long-term outdoor performance, it will return straight if stretched, will not fray, and will wear season after season. It's also suitable as a replacement cord for most clothesline brands — not just SwiftDry.For best results, tension using Gripple Tensioners.
