Chain knocker with ring and 16mm T-slot (5/8"), various chains

The chain knocker is one of the most important drain cable tools of all. This version for 16mm drain cables has a ring through which it is guided in the pipe and is thus optimally aligned in the pipeline. The ability to bend is of course very limited, which is why chain knockers with ring are only suitable for long, straight pipes. This chain knocker 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. The chain knockers also always be used for the final cleaning of the pipe after extensive drain cleaning. The chain knockers generally only be used with reinforced drain cleaning cables.

The chain knocker with ring for 16mm drain cleaning cables is available with 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 chain knocker with ring is thus compatible with all T-Nut systems from ROWO, ROTHENBERGER, rak, RIS, REMS, RIDGID, Rioned Victor, etc.
