Extension piece with T-Nut couplings

The extension for T-Nut drain cables is an intermediate piece used to provide a drain cable tool with a coupling at the tip with another tool. It is suitable, for example, for the chain knocker with male coupling or a brush tool with a pin coupling at the tip. The widely wound core increases the flexibility of the interconnected tools. This makes a design, e.g. with a sawtooth blade auger or a ball head miller in front and a brush tool behind it, much more flexible and easier to glide through the tube.

The extension piece is available in 16mm or 22mm diameter and has a corresponding pin and groove coupling at the ends. The effective extension is 18cm for the 16mm version and 20cm for the 22mm version.
