I've been looking for a source to get more of these skimmer baskets and socks for my pool, but it is proving elusive. PB has been little/no help, and all the web searches I've done still don't seem to come up with an exact match. PB used almost exclusively Pentair products in the design, but I cannot find ANY identifying part number on the basket. The trick seems to be the two faceted edges around the flange which allows the basket to lock into the skimmer housing. Any info would be most appreciated!
