This chain is meant for PVC (ABS) plumbing pipework. It does not have the hard metal bits which would be too aggressive for PVC (ABS), yet is still the perfect tool for blockage removal and descaling of PVC pipework.
They are made from stainless steel to prevent oxidation and use centrifugal force to center the tool inside the pipe.
The Plain Chain Knocker for PVC (ABS)pipes, is adjustable and mounts easily to 6mm (1/4"), 8mm (5/16"),10mm (3/8") & 12mm (1/2") flex shaft, with set screws.
Suitable for cleaning pipes from 32mm (1.3") to 200mm (8") depending on which size you choose.
The unit has three individual chains per set and is manufactured from 4mm thick stainless steel links. Chain links vary according to the application/pipe size (the bigger ones have 3 chains, the medium ones have two, and then the smaller ones have one chain).
Product pictures may vary in color and design depending on the size and diameter that you order
