Chain knocker "ultra flexible" with carbide,16mm T-Nut

The chain knocker is one of the most important drain cable tools of all. This version for 16mm drain cables with T-Nut coupling  is extremely flexible and short to enable improved arc mobility. It has 2 chains with carbide / widia carbide teeth, which efficiently remove even hard deposits. In addition,  chain knocker is also available with 4 such carbide chains (from DN70 mm). It is also suitable for preparing pipe renovations with liners. By rotating the chain knocker over the drain cleaning cable, the chains throw themselves outwards onto the wall and remove all forms of hard incrustations.
The coupling of the chain knocker is a beveled 16mm T-Nut coupling for connection to 16mm drain cleaning cables. It is compatible with all T-Nut systems from ROWO, ROTHENBERGER, rak, VIRAX, RIS, REMS, RIDGID, Rioned Victor , etc.
