Stormwater finishing collars and grates collect surface water and direct it into drainage pipework. The collar forms the visible surround and supports the grate, which helps keep larger debris out of the pipe.
In-pipe outlets fit inside matching pipe. Female socket outlets fit over matching pipe. Offset designs position the outlet away from the centre of the grate to accommodate pipework that is not directly below the surface inlet.
The surface dimensions describe the collar and grate. The final stated size and connection type identify the pipe connection.
Suitable for non-pressure surface-water drainage using matching PVC stormwater or DWV pipework.
