This fit perfectly in my skimmer. I unscrewed the bottom, took out the pump motor, put this plate in and screwed the bottom ring on tight and i have no leaks and my water flow to my new filter improved. Glad i found this as the other piece which is the big screw on cap costs more than $12 more. I bought this to help convert the filter that came with my Summer Waves pool to a sand filter.
