The Quick4 Plus™ All-In-One 12 Endcap may be used at either end of the chamber row for an inlet/outlet or can be installed mid-trench. The mid-trench connection feature allows construction of chamber rows with a center-feed, as an alternative to inletting at the ends of chamber rows. Center-feed connections allow for easy installation of serial distribution systems. Pipe connection options include sides, ends or top.
