Klir DI-4 Filter Roller - Which Collar should I use for Waterbox 90.3 sump?

[landonbeau]

I am trying to figure out if my Klir DI-4 Filter Roller is seated correctly in my Waterbox 90.3 sump. Should the rounded collar be sitting above the sock holder like this?

The roller comes with these other collars, but none of them fit my sock holder. Maybe it's okay for it to sit a little above the holder like this?

Mine sits a little proud on top of the filter sock hole in my Waterbox 110. The tabs shown in your picture should rest in each of the notches

@Ajayabb Thank you for the response! Didn't notice the tabs weren't pushed in the notches. Otherwise, I guess that's how it should look.
