Confirm your filter model number on the tank label before ordering to ensure you have the correct assembly for your specific ProSeries unit.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-18 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":54308416651539,"sku":"SX242MA1S","price":125.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-lateral-holder-assembly-for-proseries-sand-filters-w3s210s-w3s310s-sx242ma1s-3.webp?v=1786005600","url":"https:\/\/poolaroo.com\/products\/haywardpoolproductsinc_sx242ma1s","provider":"Poolaroo","version":"1.0","type":"link"}
