Ensure every DE filter grid sits exactly where it should with the Pentair FNS Plus Grid Locator Spider. This lower retainer holds each grid in proper alignment inside the filter housing, preventing shifting that could allow unfiltered water to bypass the media. Constructed from resilient materials built to handle continuous exposure to pool chemistry, it delivers dependable grid retention for both residential and commercial filtration setups.

Key Benefits

• Precision Grid Alignment: Anchors each DE filter grid in its designated slot, eliminating movement that could create gaps and compromise particle capture during filtration cycles.
• Noticeably Clearer Water: When grids stay perfectly positioned, every square inch of diatomaceous earth media works as intended, producing visibly improved water transparency and a safer swimming environment.
• Prevents Costly Downstream Problems: A deteriorating grid locator spider allows grids to drift out of position, which accelerates wear on adjacent components and degrades filtration output. Timely replacement preserves system efficiency and helps you avoid expensive secondary failures.
