{"product_id":"extension-collar-u-3","title":"Pentair Extension Collar U-3","description":"\u003cp\u003eThe Pentair WC37-503P is the skimmer lid extension collar for U-3 skimmers. It is the ring that sits between the skimmer body and the deck surface and gives the lid a level seat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eSkimmers are set at whatever depth the pool build put them, and the extension collar makes up the difference so the opening finishes flush with the deck. Once the collar cracks, the lid no longer sits square and either rocks underfoot or drops into the throat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eCheck that the skimmer you are working on is a U-3. Skimmer collars are not interchangeable between bodies, so match the skimmer first, and note this listing is the collar on its own rather than a collar and lid set.\u003c\/p\u003e","brand":"Sta-Rite","offers":[{"title":"Default Title","offer_id":48634151895252,"sku":"SWQ-25-1587","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_999df057-3b97-45af-b12c-cdc863a3d711.jpg?v=1788825806","url":"https:\/\/www.activepoolsupply.com\/products\/extension-collar-u-3","provider":"Active Pool Supply","version":"1.0","type":"link"}
