Aibole PET Expandable Braided Sleeving 25Ft-1/8 inch Wire Loom, Braided Cable Sleeve Wire Wrap,Black&Red

This doesn't fit over a standard RJ45 plug without ripping and fraying. Works good if you sleeve the cable before crimping though.

Use this stuff lots. Great for protecting wire exposed to any possible abrasion. Trailers, tractors, etc. Expands to accommodate install, connector size change etc. recommend, I use a lot so a roll is nice

Basically a giant Chinese finger trap. I understand it is supposed to heat shrink, but you risk damaging your cords if you heat it enough to prevent fraying, and no matter where you heat it, it is inconvenient. Maybe I am wrong, but there are no instructions to tell me otherwise. Would be 1000x better if it came with some kind of sealer or clasp for the trimmed ends, or with just basic instructions.

Worth it.

The wrap does the job but is much thinner than it's industrial version.Only issue I had was that after it's been cut it quickly turns into loose strands.When heating the end to melt the strands together in an effort to avoid them unwinding, the strands become a lump of plastic very quickly due to them being so small.Not a bad product but I'd look for the heavier duty option in the future.
