It also collects filtered water and directs it back to the return line without allowing sand to pass through. Replacing a cracked or broken lateral restores proper flow distribution and prevents sand from entering the pool.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eHayward Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eSX164DAS\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #ffffff;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eFilter Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e16\"\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eUPC\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e610377446969\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eFits Into\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n  \u003ctr style=\"background-color: #f8f9fa;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eBrand\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eEquipment Line\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eModel \/ Part Number\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eNotes\u003c\/strong\u003e\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr style=\"background-color: #ffffff;\"\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eHayward\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eProSeries 16\" Sand Filter — Top Mount\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eW3S166T\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003ePosition v1 #6\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cem\u003eCompatibility is based on Hayward parts documentation and available OEM records.

If one lateral shows wear, inspect the remaining laterals before reassembling the filter, as multiple laterals on an older filter often reach the end of their service life at the same time.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-18 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":54308416356627,"sku":"SX164DAS","price":127.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/hayward-folding-lateral-assembly-for-proseries-16-sand-filter-w3s166t-sx164das-3.webp?v=1786702765","url":"https:\/\/poolaroo.com\/products\/haywardpoolproductsinc_sx164das","provider":"Poolaroo","version":"1.0","type":"link"}
