Measuring roughly 37 inches in length, the rod threads directly through the center axis of the grid nest, binding the heavy top distribution manifold tightly to the bottom support locator.\u003c\/p\u003e\n\u003cp data-path-to-node=\"3\"\u003eWhen the included compression hardware and specialized washer are tensioned down at the apex using the system's holding wheel, the rod locks all eight pleated D.E. grid elements into a perfectly rigid, parallel circular matrix. This physical compression ensures that individual grids cannot flex, shift, or rub against one another under heavy hydraulic pump surges or reverse-flow backwash cycles. By maintaining absolute structural alignment, it prevents water from finding gap paths around the elements, guaranteeing that all water is forced through the D.E. media bed for micro-particulate filtering down to 3 to 5 microns.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"5\"\u003eWeight and Shipping Profile\u003c\/h3\u003e\n\u003cul data-path-to-node=\"6\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,0,0\"\u003e\u003cb data-path-to-node=\"6,0,0\" data-index-in-node=\"0\"\u003eActual Product Weight:\u003c\/b\u003e Approximately \u003cb data-path-to-node=\"6,0,0\" data-index-in-node=\"37\"\u003e1.0 to 1.3 pounds\u003c\/b\u003e.
