This genuine original equipment manufacturer (OEM) part is designed explicitly for the \u003cb data-path-to-node=\"0\" data-index-in-node=\"334\"\u003eSystem:3® SS-Series Model S7S50\u003c\/b\u003e sand filter, which utilizes a 21-inch circular tank footprint.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"1\"\u003ePrimary Operational Role\u003c\/h3\u003e\n\u003cp data-path-to-node=\"2\"\u003eThe complete underlying filtration grid of the S7S50 tank requires an array of \u003cb data-path-to-node=\"2\" data-index-in-node=\"79\"\u003e16 individual laterals\u003c\/b\u003e radially slotted into the central collector hub assembly (part number 24900-0100S). Measuring approximately 3-7\/8 inches in length by 1-1\/4 inches in width (\u003cspan class=\"math-inline\" data-math='3-7\/8\" \\times 1-1\/4\" \\times 1-1\/4\"' data-index-in-node=\"259\"\u003e$3-7\/8\" \\times 1-1\/4\" \\times 1-1\/4\"$\u003c\/span\u003e), each single finger features micro-molded V-groove slots along its outer face.\u003c\/p\u003e\n\u003cp data-path-to-node=\"3\"\u003eIts primary operational role is to establish an absolute mechanical media-barrier during daily pool filtration cycles. As pressurized water pushes through the deep sand bed, these laterals gather the purified fluid while preventing the fine silica sand media from passing into the internal lines. The collected clean water is then channeled directly into the central standpipe and returned to the pool. During backwashing, the laterals distribute a reverse high-velocity flow to lift and fluidize the sand bed, releasing trapped debris out through the waste line.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"4\"\u003ePerformance \u0026amp; Materials\u003c\/h3\u003e\n\u003cp data-path-to-node=\"5\"\u003eBy distributing hydraulic pressure uniformly across the base of the tank, this radial configuration optimizes water turnover, prevents media dead-zones, and eliminates destructive fluid tunneling. Built to remain buried under hundreds of pounds of abrasive media, this component handles continuous system pressures up to 50 PSI and resists cracking under sudden pump startup surges. Injection-molded from a heavy-walled, high-impact polymer composite, it fully resists chemical bleaching, material brittleness, and advanced corrosion from constant exposure to pool sanitizers like chlorine, bromine, and routine seasonal acid washes. Due to its ultra-compact, hollow plastic frame, this individual finger carries a net product and shipping weight of approximately \u003cb data-path-to-node=\"5\" data-index-in-node=\"764\"\u003e0.04 to 0.05 pounds\u003c\/b\u003e (about 0.64 to 0.80 ounces).\u003c\/p\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53720695210095,"sku":"24900-0002","price":22.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/media_91e8e605-2e63-4430-a89f-83c781fcb9b1.webp?v=1783437545","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-21-s7s50-filter-lateral-assembly","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
