Short chain knocker with 16mm T-Nut, various chains

The chain knocker is one of the most important drain cable tools of all. This version for 16mm drain cables is kept extra short to allow for improved arcing. The chain head is available with different chains and can therefore be used for different purposes. Smooth chains are suitable for PVC and clay pipes, chains with spikes for steel, cast iron and concrete pipes. By rotating the chain knocker over the drain cleaning cable, the chains throw themselves outwards against the wall and remove incrustations, deposits, grease and other pipe blockages. It should also always be used for final cleaning of the pipe after extensive drain cleaning. The chain knockers generally be used with reinforced drain cleaning cables.

The short chain knocker for 16mm drain cleaning cables is available with 3 or 4 smooth chains or cam chains (with spikes). The coupling is a bevelled 16mm T-Nut coupling for connection to 16mm drain cleaning cables. The short chain knocker from ROWO is thus compatible with all T-Nut systems from ROWO, ROTHENBERGER, rak, RIS, REMS, RIDGID, Rioned Victor, etc.
