The RELINER Manhole Channel Repair System is a molded fiberglass flume with a smooth sewer pipe interface used to rehabilitate inverts without flow interruption, and can also be used in new construction. The field-installed modular components bolt together with minimal tools, are adaptable to a wide range of field conditions and manhole sizes, and are compatible with all current field manhole-lining systems. The full-depth lined channels are high flow and easy to clean and maintain. Standard 8- and 12-inch-depth channel sections fit through a 24-inch manhole frame and will accommodate 6- through 12-inch pipes. Larger sizes are available. 800/508-6001; www.reliner.com.
