Review: Our project looks like it was purchase off the shelf by a refined ... - This product is so well made it blows me away. I thought the fibers would Frey too much..l they don't. When you cut them to size, be sure to take a lighter to them to burn the ends down a bit to seal them off, when I did this the ends sealed so well and were very smoother for our project. We needed this to be the case since the look and feel of them was very important for our product to be sell able. Very well made. Our project looks like it was purchase off the shelf by a refined company with much longevity.
Review: It is easy to run wires through this if you know the ... - This stuff works well to keep wires bundled together and makes projects look professional. As the title says, this is made from polyethylene, a type of flexible plastic. It probably wouldn't hold up well in a really hot environment (in contact with a car engine, for instance). When you cut it, the ends fray, but a few seconds with a lighter will melt the individual strands together. It is easy to run wires through this if you know the trick... just push inward from both ends and this will expand, then slide the wires through. It expands to twice its nominal dimension, so figure out how big you need the wires to be, and make sure the connectors will fit through twice the diameter. One more thing -- I inadvertently slid a finger all the way in to this before I realized this is essentially a really effective Chinese finger trap. I had to cut it to get it off my finger.

- Protecting wire harnesses is easy with the 150% expandability which makes installation simple and efficient.

## Questions & Answers

**Q: Am I able to run the wires of my mod mic and the wires of my headphones into one sleeve?**
A: As long as the wires (and plugs if they are not detachable) fit within the size of the braided sleeving, you can put them into one sleeve. Make sure to measure the diameters of your wires to see what size braided sleeving you should use.

### ⭐⭐⭐⭐⭐ Works well
*by A***A on October 13, 2015*

Used this wrap speaker wire for speakers to my computer that I have connected to small amp. I didn't have to worry this time about ends fraying because I used heat shrink. In other projects a hot knife always works best to avoid fraying when cutting.
