Blast Through Clogs with Chain Knocker Power Chain knocker is the go-to tool when regular drain snakes just bounce off tough blockages. This heavy-duty attachment has linked metal chains with carbide-tipped heads that spin at high speed, smashing and scraping away grease, scale, roots, and hardened debris inside cast iron, clay or PVC pipes. It’s especially effective for commercial lines or stubborn residential clogs that chemicals and standard cables can’t handle. Homeowners and plumbers love it because it clears pipes fast without damaging the line. See the chain knocker in action in this image – watch how it chews through buildup and leaves the pipe clean and flowing again. Ready to tackle your toughest clogs?
