Series 04 — Slack absorbing

Elastic Strap

The Easooty elastic strap is a round elastic cord — a braided polyester cover over a natural-rubber core — that shortens under tension and lengthens when released, so it pulls itself tight over a load without re-tensioning. It is 8 mm in diameter and 1 m long, rated 16 kg safe working load and 60 kg breaking strength, with a black hook at each end. Manufactured by Ningbo Yishu Trading Co., Ltd. in Ningbo, China, it is a soft secondary restraint for loads already held by a ratchet strap or a fixed anchor, and it is available in custom lengths and colours.

About this product

What makes an elastic strap different

A round cord behaves differently from flat webbing, because the stretch comes from the rubber core rather than from the weave. The braided polyester cover carries the abrasion and takes the pull of the hook; the natural-rubber core inside shortens the cord under tension and lets it back out when the tension is released. The result is a strap that is always snug: if the load settles in transit, the cord takes up that movement without being touched. This is why it is fitted as a secondary restraint. It is not a substitute for a ratchet strap — a cord that stretches as the load comes on is not a restraint at high load — but it reliably removes the slack from a load that is already held.

Where to use it, and where not to

Use it for the loads it is rated for: a tarpaulin corner lifting in the wind, a tool that shifts in a tray, sacks of firewood or produce settling in a pickup bed, a board strapped to a roof that works loose after the first hundred kilometres. With a 16 kg working load this is a light-duty strap, meant for bundles and covers rather than for the primary restraint of a heavy machine. Do not use it to hold a load that has to stay held through a road incident, and do not pull it past its working load to drag a load into place. If the load needs a rating above 16 kg, that is a ratchet strap’s job.

Stretch and service life

The cord is elastic: it lengthens under load and shortens again once the load is off, and how far it stretches depends on the load and on how the cord is built — which is why we publish the working load and the breaking strength rather than a stretch percentage. The relationship between those two figures is the one that matters: 16 kg of working load against 60 kg of breaking strength. Natural rubber ages: it hardens, then loses elasticity, then cracks. Stored indoors away from sunlight and heat, an elastic cord keeps its properties for several years. Left on a roof rack through two summers in full sun, it will need replacing far sooner. We do not put a shelf life on the label because it depends entirely on storage, but we will tell you honestly: buy a spare set, and replace them with the vehicle rather than waiting for them to fail.

Materials and construction

The cord is a braided polyester cover over a natural-rubber core, made as one piece rather than as a laminate. The cover keeps the abrasion away from the rubber and takes the pull of the hook; the core does the stretching. Each end is closed with an injection-moulded sleeve over the cord and a black hook, so the load path runs through the sleeve and the core rather than through stitching. Standard colour is red. Custom colours are made to order, and for private-label buyers we can print the hang card and polybag and apply your own carton markings.

Where it is used

  • Red elastic strap holding a bubble-wrapped bundle against a carton

    Bundling light cargo

    Bundles, sacks and shrink-wrapped pallets. The elastic takes up the slack as the load settles, and the hook holds it without a ratchet.

  • Red elastic strap running over the lid of a cardboard box, its hook in view

    A second line of restraint

    Over a load that already carries a ratchet strap, to take out the movement that appears in transit without adding another rigid buckle.

Frequently asked questions

  • Can an elastic strap hold a heavy load on its own?
    No. The 60 kg breaking strength is not a working load: the cord stretches as the load comes on, so it gives way progressively rather than failing predictably. The figure to design around is the 16 kg working load. Use it as a secondary restraint alongside a ratchet strap, a cam buckle strap or a hard tie-down point — that is what it is designed for. If you tell us the load and the restraint you already have, we will tell you honestly whether a strap is needed at all.
  • How much does it stretch?
    It stretches under load and shortens when the load comes off — that is the whole point of it. The two figures we design and quote against are the 16 kg working load and the 60 kg breaking strength, rather than a stretch percentage, because the elongation of a given cord depends on the load and on the length you take. If you need less movement, use a shorter length, or add a rigid strap instead of relying on the cord to hold a position.
  • Does rubber age in sunlight?
    Yes. Ultraviolet light hardens natural rubber, and a hardened core loses its elasticity before it visibly cracks — so an old strap can hold tension when you need it to release. Do not leave a spare set on a roof rack through summer; store them indoors, and replace them on a schedule rather than on failure.
  • What lengths and end fittings are available?
    1 m is the standard length, with a black hook on each end; other lengths are made to order. The 8 mm diameter is fixed for this series. For a custom colour, the minimum quantity is typically 500 metres of cord, and we can print the hang card and polybag for private-label buyers.
  • Can I get private-label packaging?
    Yes. This series is assembled from braided cord and standard fittings, so private-label work adds sewing and packaging cost only — no tooling. We can print the hang card and polybag and apply your own carton markings.
