Abstract:
1. A trench drain assembly comprising: an elongated flow channel extending longitudinally between first and second ends and including sidewalls that extend upward to top surfaces, wherein the sidewalls have a constant height throughout the entire length of the channel and include spaced lugs that extend inwardly; and a frame for supporting the channel in a trench and including two longitudinal extending sidewalls connected by lateral braces, wherein the sidewalls have: spaced lugs that extend outwardly; bottom surfaces for receipt on the top surfaces of the sidewalls of the channel; and a height that increases consistently and gradually between first and second ends of the frame so that the frame creates a gradual slope for the channel to properly drain, wherein the lugs of the channel and frame are sized and configured such that, in a pre-assembly position, the lugs do not interlock, and, when the frame is slid longitundially to an assembled position, the lugs create an interference fit to secure the frame.
