The Hummingbird Micro Chain Cutter from KEG Technologies is intended for use on lateral service lines ranging in diameter from 2 to 6 inches. It connects to 1/2-inch jetter hose and requires 12 gpm at 2,000 psi to operate. It fits in most clean-outs and can negotiate a 3-inch sweep elbow or tee connector due to its small size and light weight. Once powered up, the nozzle will hover in the pipe and remove roots, grease, hard deposits and even baby wipe cloths while maintaining the structural integrity of the pipe being cleaned. 866/595-0515; www.kegtechnologies.net.
