Pro-Graad FlowFixer T-216-S 2" Chain Knocker Drain Cleaning Head Slotted Connector | Heavy Scale Removal | Fits 3/8”, 1/2" or 9/16” Cables, Commercial & Residential Use

Pro-Graad FlowFixer T-216-S — When You Need More Than a Snake. Some lines don't just need unclogging. They need rehabilitation. Years of mineral scale, rust, and hardened buildup don't yield to a standard auger — they need to be beaten off the pipe wall. That's exactly what the FlowFixer T-216-S chain knocker is built to do. As your cable spins, the T-216-S's steel chains extend outward through centrifugal force and whip the interior pipe walls with each rotation. The result is impact plus abrasion across the full pipe circumference — not just down the centerline. It's the difference between punching a hole through debris and actually cleaning the pipe. Where It Fits in the Professional Drain Workflow: 1. Open the blockage with your auger or root cutter, 2. Run the T-216-S to strip scale and clean walls, 3. Finish with a brush or flex shaft polish if needed. This tool is for professionals who understand the difference between "drain open" and "drain clean." Plumbers, drain technicians, boiler room maintenance crews, and MRO specialists running sectional or drum machines will find it fits exactly where it's needed. [IN THE BOX]: 1 each Pro-Graad FlowFixer T-216-S 2" Chain Knocker Drain Cleaning Head with Slotted End Connector | Heavy Scale Removal | Fits 3/8”, 1/2" or 9/16” Slotted End Cables. [AGGRESSIVE CHAIN-WHIP CLEANING ACTION]: Centrifugal force swings hardened steel chains outward as the cable rotates, delivering full-circumference impact and abrasion against pipe walls. Eliminates mineral scale, rust, and hardened deposits that standard cutters won't touch. Built for jobs that demand vigorous action, not just clearing a clog. [PROFESSIONAL 2" WORKING DIAMETER]: Sized for 2-inch pipe ID, this chain knocker restores full pipe capacity by cleaning wall-to-wall — not just boring through the center. Ideal for boiler tube cleaning, scale rehabilitation, and restoring flow in heavily built-up drain lines. [BROAD CABLE COMPATIBILITY]: Compatible with 3/8", 1/2", and 9/16" Slotted End cables for broad compatibility across electric drain machines. [HEAVY-DUTY STEEL CONSTRUCTION]: Steel body with free-swinging chain links engineered to absorb thousands of impacts without failure. Compact head design allows entry through standard clean-outs. Replaceable wear components extend tool life. Approximately 1/4 lb — built dense, not bulky. [STEP 2 IN YOUR CLEANING WORKFLOW]: The Flow Fixer T-216-S isn't your first-pass cutter — it's what you run after opening the line to knock loose scale and restore pipe ID. Use it between your auger/root cutter and finish brush. Not recommended for thin-wall PVC or severely corroded pipe. Start at low RPM; feed slow; let the chains do the work.
