Wire harness building materials

Jun 06, 2024 Last reply: 1 year ago 7 Replies

Went looking for some spiral cable wrap to build a few simple wiring harnesses. ISTR it was pennies per foot some years ago, so I expected dimes per foot now.



Turns out it's dollars per foot for the spiral stuff, but slit corrugated hose is much cheaper, roughly what I expected for spiral.



Anybody have a clue why? The convoluted material looks a lot slower to make. I tend to think it's inferior mechanically, and certainly is bulkier.



Thanks for reading, and any ideas...

As for your question of cost............... Sorry, but I don't know. I would have to guess it has something to do with supply and demand!!

Hope the above helped with someone's knowledge base!! :-)

Depends on whether it needs to be an approved or listed component in a certifiable wiring assembly.

Anybody can slit extruded tubing. Materials certified for flammability or chemical/thermal/mechanical properties in a specific application are harder to devellop and to market.

You have to specify the wiring materials - why should the wrap be excluded from this stringency?

Some clue as to what diameter and material you're looking for would be helpful. Looking at what a Google image search dredged up, I don't see anything that costs "dollars per foot".

For example:

$15.13 / 100 ft in 3/4 inch diameter LDPE.

Convoluted material? Maybe a more specific material description will yield a less vague answer.

That actually looks like a good deal but 100 feet is waaay too much. The disclaimer about residential shipping surcharges makes me wary.

Here's a fairly representative example:

$2/foot, not locally in stock but it appears pickup is free if I'm willing to set up an online account.

product I ended up buying (from a local auto parts store) looks similar and was about $5 for 7 feet, half inch ID.

I should admit the last time I bought spiral wrap it was from the local Radio Shack store..... the real puzzle is the availability disparity. The corrugated stuff looks a lot harder to make, bulkier and gives the wires less support. Why is it easier to find?

Temu sells similar stuff for $1.98 delivered.

My initial search was aimed at local retailers. In the end I found what I was looking for on Amazon. but it took a couple months to assemble a $35 order....

The product you located looks similar, I agree it's extremely useful.

I've found this really helpful for a lot of our rack building projects:

They have a very wide variety available.
