The Bulldog 37 Series cross jet nozzle from Enz USA has been designed for operation with both fresh and recycled water. The cross jet design concentrates on opening completely blocked lines, frozen pipe and interlaced root intrusions. An integrated oil-free braking system results in a low wear-and-tear operation and controlled numbers of rotation. It is available in 1/2- and 3/4-inch connecting threads, and is effective on pipe diameters ranging from 2 1/2 to 8 inches. 877/369-8721; www.enzusainc.com.
