Techflex expandable nylon sleeving is ideal for finishing your DIY cable project, giving it a "professional" look. The color available is black only, and is available in 5 sizes. The cleanCut Techflex is a finer monofilament mesh than the standard version, looks much nicer, and has a more fabric-like finish to it. Very nice. It's a good idea to order 30%-50% MORE Techflex than you think you may need, since it will shorten when expanded around your work.
* Notes for DIY'ers:
Flavor 1 or 3 power cables - use 1/2"
Flavor 2 or 4 power cables - use 3/4"
Most interconnects - use 1/4" to 3/8"
CHeLA Speaker Cable - use 1 1/4"
