Agla, I did a little research before starting this one, and the suppliers I saw didn't have a channel system that would allow the water to daylight at the same grade as the top of the grate, so I opted for this paver system for the grating instead.
In fact, the company I bought this from (Ironsmith) also had the sloped channel. But my need was for a channel that could empty onto grade...nobody had that.
Steve, yeah, I'm not 100% satisfied, but it's much better than what we were going to do there. And it was fun to try something a little different.
