Electricians, hobbyists, automotive technicians, and DIYers all run into the same problem: tubing that's too thick, too thin, or sold only in bulk rolls.

Diameters range from 0.6mm (≈0.024\") up to 80mm (≈3.15\"), covering everything from fine signal wires to large battery cables and conduit bundles.
