Absolutely. We sell to all states of Australia.We send our cords all around QLD, NSW, VIC, NT, WA, ACT, SA and not to mention Tazzie 🙂 And even our good mates in New Zealand – they are a bit like a state of Australia. So we count you too. 🙂 *Free Delivery does not apply to New Zealand Orders.
We have great deals with major local and national courier companies for reliable deliveries almost everywhere.
I am in another country can I buy my cords from you?
Absolutely. We sell to most countries.
We have great deals with major international courier companies for reliable deliveries almost everywhere around the globe.
Can I buy curly cord on the roll E.G. 100m?
No. It seems to be a common misconception that curly cords come on a roll like straight cable. But Curly cords are not sold like raw cable.
(i.e. supplied on bulk rolls and priced per meter) but rather each cord is individually formed. We also provide straight tails at each end of the cords to allow for termination.
What are the shortest and longest cords you make?
The retracted lengths we make range from 25mm (1”) to 1800mm (1.8m) (6’)
How far will my cord stretch?
Depending on the construction of the cable itself and the parameters of the coil, the maximum extension ratio can vary quite a bit. As a safe rule of thumb we suggest a 3 to 1 ratio. E.g. a 1m coil will extend to 3m. However that rule is not set in stone and some of our cords are capable of extended much further E.G. 4:1 and even some up to 7:1 when specifically designed that way.
Something to keep in mind:- When we design and make the cords to extend further we usually sacrifice the retractability or the “Spring” of the cords.
What happens if I need them longer?
We can add longer straight tails (we can increase tail lengths to 1m or longer if need be.) In fact the extend length is usually more important than the retracted length anyway. So we can usually adjust the parameters of the coil to allow it to extend further as well. In addition you could also join multiple cords together to reach the desired length.We have a new procedure where we basically make two cords back to back with a short length in between them. This can produce a cord that can be up to  3.6m Compressed. It is a much more difficult procedure than standard, however if you really must have longer cords, this may be the best option.
What’s the best way to handle my cords?
Just because the cords look like steel springs, please don’t treat them like one. Please bear in mind that these cords do in fact contain electrical/electronic wires. And as such if handled roughly can be damaged. To ensure long life please treat the cords with respect.Will my curly cord return to its original state?
In most cases Yes. Provided you choose the right cord for the job, and the cords are not overextended.
However this is not necessarily the case with most of the PVC cords. These types of cords are not designed for any use where high retractability is required. They are simply used for “cosmetic effect” i.e. to look nice. Whilst they are curly cords, they are not necessarily self retracting. If you want the cord to return to its fully compressed state, you should consider using one of our higher quality cords.What happens if I over stretch the cord?
If you over extend the cord, it is likely the cord will no longer return to its fully compressed state, and in some cases the internal wires may be damaged.Are the coil I.D. (Inside Diameter) and O.D. (Outside Diameter) important?
Whilst not normally important to the average user, there are instances where it can be significant. For example the cord O.D. is important if the cord is being mounted inside a channel. And the I.D. is important if it is being mounted around a tube. These are probably the only instances where you would need to concern yourself with it. Otherwise I suggest leaving that up to us. We are in the position to determine the optimum diameters, based on the other construction parameters.
If you have such a situation, I suggest you be sure to advise us of this requirement on your e-mail.

On your website you talk about conductor size. How does that work?
Generally we refer to the conductor size by Cross Sectional Area.
To work out the cross sectional area of a wire you need to know the strand size (usually expressed as the Diameter), and the Number or strands.

You take the strand diameter, and square it (multiply it by itself), then multiply this by 0.785, then multiply this by the total number of strands. This my sound complex, but it’s really simple in practice.

In the automotive industry Another common way to refer to wire size is to use the measurement across the wire (including the insulation). As in “4mm auto”. The difficulty here is the insulation thickness varies between different cables. This is largely based on voltage rating, and varying dielectric strength of the insulation materials as well as different Various Standards and relevant manufacturers specifications.
For example “4 mm auto” can be 2 mm²,  But we have heard of it ranging from 4 mm², 2 mm², 1.85 mm², and even 1.25 mm²,
All of which would have a large baring on the current carrying capacity of the cord.
That’s why we normally talk about Square mm (mm²) as there is less chance for ambiguity.

You have a very large range. Do you have all of those in stock?
No. This site is designed to show some of the various types and options available. Because the highly custom nature of the cords, Most of our cords are made on demand (made to order). However we do have several varieties in stock which have become “standard” lines, as well as overruns and other incidental stock.

I want a cord that is not listed. Do you have others?
Absolutely. We have many other cords that are not listed on the website. In fact we probably have the largest range of cords available, and the range is ever expanding! Furthermore if you feel we there is a need for a particular type of cord that we don’t know about, we would love to hear about it!

I have my own straight cable/cord. Can you coil it for me?
Possibly. Some cable work better than others. Whilst we can process most cable, the finished results vary dramatically. A Very small number of cables coil very well (Some off the shelf Polyurethane cables), Most normal cable will not hold a coil. Some will not withstand the coiling process itself, and others can hold the coil, but produce coils that have limited (or non existent) expansion and/or retractability.
We have Many years of experience working with cables and have many of our cables especially manufactured for the process.
As I love to say… “One test is worth 1000 opinions.” So…I would be happy to run a trial for you. Please feel free to send me your sample.

I am not really sure what I need. Can you help?
Absolutely. In order to help you, it is beneficial to understand how you will be using the cords. So an overview of your application is essential.
Please just drop me an E-Mail with your details together with details of the application, and I will be happy to work with you to arrive at a suitable design.

  1. Hi,

     i am looking for a curly core 2mm 6 core 400mm long Not extended.


    Can you help .


    Regards Rob

    1. Hi Rob,

      Thanks for your inquiry.

      Can you clarify…when you say 2mm….is that 2 square mm (mm²) or 2mm auto?

      Our “standard” lengths are 300mm, and 500mm coils, plus 150mm straight tails. or does it need to be 400mm for a specific reason?


      All the best…
