Abstract
A drainage channel includes a conduit defining a lengthwise extending opening and an inlet defining a passageway in fluid communication with the opening. The inlet may have an exterior surface that defines a plurality of pockets spaced apart in the lengthwise direction. Concrete or another hardenable composition may fill these pockets to secure the inlet in position. The drainage channel may also include at least one saddle for supporting the conduit and an engagement member for preventing relative rotation between the conduit and the saddle. The saddle may extend about a majority of the conduit. In this regard, the saddle may include a base and a pair of upstanding arms extending outwardly therefrom. The arms are disposed on opposite sides of the conduit and converge thereabout so as to engage the conduit and prevent the conduit from floating as concrete or another hardenable composition is poured thereabout.
