You’re on site staring at a stubborn clog. You grab one of our chain knockers, lock it into the flexible shaft maybe add milling head in front, slide the whole thing into the pipe and watch it power through in just seconds. From a home bathroom sink to an industrial main line, these chains handle every job without breaking a sweat.

Our lineup has everything you need. Choose a Plain chain knocker to make your way through soft material pipes like PVC/ABS while cleaning it effectively, or use X-Tip/Croco when dealing with the lines made from harder materials (cast iron etc.) to get results you have no idea you can get. Since pipes come in all sizes, pick a lighter chain (Light) for small residential lines or go heavy-duty (Heavy) when you’re working on big commercial drains. Remember to choose the correct Flex Shaft length and diameter depending on the task as well!

Whether you’re dealing with metal, clay or PVC, our chain knockers adapt to take on mineral scale, sludge and roots without wearing out or damaging the pipe. Swapping chains takes about a minute so you can spend less time fiddling with gear and more time clearing clogs.

Don't forget the Drill headed chain knockers like Drill Headed X-Tip Chain Knocker!

Plus, every chain knocker is handmade in Finland using premium materials to shrug off rain, mud and early-morning chill. We keep them all in stock online. No hunting down multiple suppliers. Everything you need is at 4Rleine.com.
