Each individual grid is constructed from high-tensile, chemical-resistant polypropylene cloth tightly stretched over an internal, injection-molded structural raw polymer frame. The narrow partial grid is strategically integrated to provide a dedicated installation gap for the filter vessel's internal top air bleed extension tube.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eWhen arranged in a circular formation and clamped tightly between the filter's top manifold and bottom locator plate, these grids create a 36-square-foot surface area. Once coated evenly with raw D.E. powder, this grid nest mechanically intercepts organic debris, fine silt, and algae spore matrices down to an industry-leading 3 to 5 microns. Replacing the entire bundle at once cures uneven pressure drops caused by isolated fabric tears, worn stitching, or mineral-calcified fabric pores that regular backwashing can no longer clear.\u003c\/p\u003e\n\u003cdiv class=\"attachment-container search-images\"\u003e\n\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\u003c!----\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"5\"\u003eWeight and Dimensions Profile\u003c\/h3\u003e\n\u003cp data-path-to-node=\"6\"\u003eBecause this kit bundles all eight individual structural fabric grids together into a single box, it carries a broad and rigid shipping footprint:\u003c\/p\u003e\n\u003cul data-path-to-node=\"7\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,0,0\"\u003e\u003cb data-path-to-node=\"7,0,0\" data-index-in-node=\"0\"\u003eGrid Height:\u003c\/b\u003e Individual grid elements measure exactly \u003cb data-path-to-node=\"7,0,0\" data-index-in-node=\"54\"\u003e18 inches long\u003c\/b\u003e (the industry-standard measurement designating a 36-square-foot Pentair tank capacity core).\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,1,0\"\u003e\u003cb data-path-to-node=\"7,1,0\" data-index-in-node=\"0\"\u003eActual Product Weight:\u003c\/b\u003e Approximately \u003cb data-path-to-node=\"7,1,0\" data-index-in-node=\"37\"\u003e13.5 to 14.5 pounds\u003c\/b\u003e for the combined bare weight of all eight nested elements.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"7,2,0\"\u003e\u003cb data-path-to-node=\"7,2,0\" data-index-in-node=\"0\"\u003ePackaged Shipping Weight:\u003c\/b\u003e Typically scales at \u003cb data-path-to-node=\"7,2,0\" data-index-in-node=\"46\"\u003e18.0 to 20.0 pounds\u003c\/b\u003e due to the wide, heavy-duty cardboard box and internal stabilization dividers necessary to shield the rigid plastic grid frames and delicate outer mesh from being crushed, snapped, or torn during transit.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53762640380015,"sku":"198081","price":380.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/59023500__99510_ffc42d84-95cd-4aef-bb59-ef91c109420c.jpg?v=1783609221","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-36-fns-plus-grid-replacement-pack","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
