Set the right inlet and outlet heights to optimize your drainage system. The Offset Outlet Adapter features an asymmetrical design to adjust the height of inflow or outflow piping to catch basin with a twist. Connects 9 in., 12 in., 18 in., and 24 in. catch basin drains to 3 in. & 4 in. single-wall corrugated pipes, sewer and drain pipes, and 4 in. Sch. 40 pipe, triple-wall pipe. Connection to 18 in. catch basin requires additional Reducer Ring (1890); 24 in. catch basin requires additional Outlet Adapter with Reducer Ring (2410). Made of high-impact polystyrene (HIPS) treated with UV inhibitors.
Applications
- Use to connect the catch basin drain to drain pipes as part of a complete drainage system
- Works with 9 in., 12 in., 18 in., & 24 in. catch basin drains
- The outlet adapter connects the catch basin to drain pipe; as part of a complete drainage system, water is captured and directed away for proper release downstream
