The End Cap/Outlet for the BG-FILCOTEN® 100 trench drain line can work in two ways. It can be used as an end cap to seal the end of the channel, or by knocking out the center it can be used as an end outlet to connect the channel to 4 in. DWV pipe. The component slides into the female end of the channel and is secured with silicone. Use the molded-in cut guides and a pair of tinsnips to cut the galvanized steel End Cap/Outlet to the desired channel depth.
