Channel Drain to Clay Gully

[mwkenna]

I need to fit channel drain to a clay gully. I'm going need to join into the side. I think I will cut a 70mm hole with a glass cutter and fit a 68mm pipe in the side like someone else has done on this forum. The problem I have is that I can't find any channel drain with a 70mm outlet, they're all 110 to fit a downpipe. Does anyone have any suggestions on an end outlet that is 70mm or a way to convert it?

Thanks!
