Get/make Custom sump

Looking to either make a sump or get a coustom one. I want to be able to run 2 7in klir filter rollers in it and i cant fine a sump that comes with 2 7in filter sock in it. Any thoughts?

My sump is a 55 gal tank that I made my own baffles and bought holders for 2 4” Sox. I’m sure you could do the same for a 7”

I have been looking and all i can find is pieceses that hang on the back or side and i do t think they would handle the weight of the klir

They have hanger for 7” Sox like you said. Your return plumbing hooks to it. It should not be a problem that I’m aware of.
