Filter floss cup....anyone make one that actually fits?

I very much want to change from filter socks to media cups with filter floss but I can't find any that fit. The Red Sea version is too small but will work, but if I turn the pump off for some reason they shift and allow water to enter around them and not through them.

Just ordered these from Marine Depot and they are so small they fall through the hole! Come on, sump and dry goods manufacturers, get together on a standard size hole and cup.....like maybe actually 4"?

What are you guys doing this using in a Trigger Sump with "4 inch" holes?

I don't use filter cups. However, I was researching them for my trigger sump. I think if you contact the manufacturer of the cups, there is some attachment or gasket that will allow you to use it with your trigger sump. Good luck!
