It is the genuine CMP replacement part.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThe grate is the internal shelf inside the feeder body. Chlorine tablets stack on top of it, which keeps the bottom of the stack clear of the water that sits in the base of the housing. That gap is part of how the feeder controls dosing: water passes through at a rate the dial sets, rather than simply soaking the whole stack.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy it wears out\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eTrichlor is hard on plastic, and the grate is in constant contact with it. After enough seasons the material goes brittle, then cracks or breaks apart. Once that happens the tablets slump into the base and the feeder starts dosing unevenly, which usually shows up as chlorine readings that swing rather than hold.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBefore you order\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eOpen the feeder and confirm which internal part has failed. The lid, the dial, the flow meter assembly and the drain plug are all separate CMP parts, and it is worth ordering everything that is tired in one go rather than shutting the system down twice.\u003c\/p\u003e","brand":"CMP","offers":[{"title":"Default Title","offer_id":48635034763476,"sku":"CTM-451-1002","price":12.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_7714e0c2-754f-43ea-9899-e3be11d419f7.jpg?v=1788840016","url":"https:\/\/www.activepoolsupply.com\/products\/cmp-powerclean-ultra-chlorinator-grate-25280-100-005","provider":"Active Pool Supply","version":"1.0","type":"link"}
