The Root Ranger root cutting nozzle from RIDGID clears obstructions from blocked drains. It can be used to cut through tough grease and sludge buildup, as well as stubborn tree roots. The single rear-facing turbo jet produces a powerful, concentrated stream of water that can be used to easily shear root obstructions clear from the drain wall. The specially engineered head allows it to push its way through tough blockages, while the rear-facing turbo jet scours the drain clean and flushes away debris. It is compatible with the RIDGID KJ-3100 Jetter, which provides 3,000 psi actual working pressure to handle large commercial and industrial drain cleaning applications. It propels a highly flexible and lightweight hose through 2- to 10-inch lines, blasting through sludge, soap, grease and sediment blockages. 800/769-7743; www.ridgid.com.
