Reef factory roller mat L size

[DTz]

Hi guys I’m bout to purchase the reef factory roller mat L size from a local seller. Issue is I’m not sure if my sump will fit. My 1st compartment is 10 inches long and 24 inches width

This is the measurement required.

Anyone have experience installing one? Don’t think my sump have sufficient space? As it is no return policy. So I need to make sure beforehand

Cut a piece of cardboard to size & double check.
I just got the medium sized one.
The 24" will handle the length , what you need is the width of the unit.
You may NOT be able to get the basket out in the sump though.
