Need help with my 1st filter sock setup

My sump is in the basement. Its a 100g rubbermaid tub. I have two 2" drain lines dumping into the rubbermaid sump, vertical straight down into the rubbermaid.



I'm wanting to start using filter socks on both drain lines, BUT since the rubbermaid sump isn't square all the filter sock holders i'm seeing won't work bc they mount on a vertical piece as if the sump where a square box.



Help me with a design plz..... thanks
