4" Filter sock roller mat

[nathanboky]

G'day, I'm looking to replace my filter sock with a roller mat, I am limited for space and wanting to use the existing sock area without any change to plumbing, is there anything available? I have a 3d printer so happy to DIY if there is a good design already.. many thanks

Check out Klir Di-4. That should fit a 4” filter sock hole.
