Just what I needed!

I have been needing a new intake sponge to cover a bulkhead strainer in one of my tanks and this fit the bill perfectly! It's a snug fit over my 1 inch bulkhead which works out perfectly so that I don't have to use anything else to hold it in place. The bigger pores also mean I don't have to pull it off as often to unclog it which is a big plus!
