Plenumline Mechanical Joint Acid Waste Systems easily displace costly and difficult-toinstall glass and metal systems. With Plenumline, time-consuming methods associated withconventional heavy and brittle systems are replaced by a time-proven mechanical joint that takes only 30 seconds to complete. Once the Plenumline nut is locked in place, the end-user is assured of many years of trouble-free service. In addition, mechanical joint systems can easilybe dismantled and reused, making Plenumline ideal for modular designs and future expansions.
