Chain knocker with ring and 22mm T-slot (5/8"), various chains

The chain knocker is one of the most important pipe cleaning tools of all. This variant for 22mm drain cables has a ring through which it is guided in the pipe and is thus optimally aligned in the pipeline. This, of course, severely restricts the bendability, which is why chain knockers with a ring is only suitable for long, straight pipes. This chain knocker is available with different chains and can thus 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 pipe cleaning spiral, the chains throw themselves outwards to the wall and remove incrustations, deposits, grease and other drain blockage there. It should also always be used finally for final cleaning of the pipe after an elaborate drain cleaning .  The chain knockers should generally only be used withreinforced pipe cleaning spirals (S-drain cables, S-SMK spirals).

The chain knocker with ring for 22mm pipe cleaning spirals is available with 4 plain chains or cam chains (with spikes). It is available with different ring diameters. The coupling is a bevelled 22mm T-Nut coupling for connection to 22mm pipe cleaning spirals. The chain knocker with ring is thus compatible with all T-Nut systems from ROWO, ROTHENBERGER, rak, RIS, REMS, RIDGID, Rioned Victor , etc.
