Hi, the sides don’t have a problem because rain runs down and off the sides ok. The middle bit is the area that fills up. Not a great design by Burstner. I think I’d only need 1 that could go just to the side of the metal bracket. There‘s enough space to get something in the low part without having to drill through the metal then.Hi ASR
I can make some to fit that. Do you just need drainage pipes in the central area where it drops down. Do you have any problems on the sides.
