Drainage Channels Drainage and wastage systems and plumbing help, advice and answers

Is it possible to install a drainage channel with angles greater than 90 degrees?

I want to install a channel around the bottom of a bay window to direct surface water from my front garden towards an existing gully that is located just to the right of the bay (it's easier for me to do this than sloping towards the street).

It'd like the channel to follow the edge of the bay but to do this I'd need to connect the corners with an internal angle of about 135 degs. The only drainage connectors I've seen online are right-angle or T pieces.

I googled, I found you can get a "jointed" drainage channel, it appears to fit around bay windows, it was about £1/inch (No, really it was around £12 for a 30cm section) Not sure how you put the fall on it.

I would opt to make the "bay area" slabs fall the same direction and install a straight drainage channel much cheaper.
