About This Item

The Pentair Spider Grid Locator (59000500) is the OEM replacement bottom grid locator spider for the Pentair FNS Plus series D.E. filters.

What It Does

The bottom spider grid locator positions and retains the filter grids at the base of the filter tank, keeping each grid element correctly spaced and aligned during operation. A cracked or deformed locator allows grids to shift, which can result in uneven D.E. coating, channeling, and D.E. passing back into the pool. Replacing this component restores proper grid alignment and filter performance.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Pro Tip

When servicing the filter for a broken or warped grid locator, inspect all filter grids at the same time. A locator that has failed due to age or chemical exposure often indicates the grids themselves are approaching the end of their service life. Replacing both together avoids reopening the filter for a grid change in the near term.
