About This Item
The Unicel FG-1002 is a single replacement full DE filter grid engineered for 24 square foot diatomaceous earth filter systems. Designed to exact dimensional tolerances with a reinforced 12" fabric grid body and a 2-notch open slot collar, it delivers a precision fit into Hayward, Pentair, Pac Fab, American Products, Sta-Rite, and Astral filter manifolds — stopping debris and maintaining the filtration efficiency your pool depends on.
⚠️ IMPORTANT: CHECK BEFORE YOU BUY
This product is a single (1) replacement DE filter grid — it is NOT a complete set. A full filter service requires multiple grids. Please verify the quantity and type (full or partial) needed for your specific filter model before ordering.
⚠️ IMPORTANT: Partial Grid Also Required for Full Filter Service (Most Models)
Most Hayward and Pentair 24 sq. ft. DE filter systems require 7 full grids + 1 partial grid for a complete re-grid. This listing is for the full grid only. Don't forget the companion partial grid — Unicel PG-1902 Partial DE Filter Grid.
Exception — Sta-Rite systems: Compatible Sta-Rite filter models use 8 full grids only — no partial grid required.

Pro Tips
- Safety first: Always turn off the pump and release all pressure from the filter tank via the air relief valve before opening the tank to replace grids.
- Measure before you order: Verify your grid length by measuring the fabric body from end cap to end cap — collar not included. Your existing grid should measure 12" to confirm FG-1002 is the correct fit.
- Check your collar: The FG-1002 uses a 2-notch open slot collar. Inspect and replace your manifold o-rings while the filter is open for best performance.
- Replacing the full set? For most 24 sq. ft. systems, a complete re-grid requires 7× FG-1002 full grids + 1× PG-1902 partial grid. Sta-Rite compatible models require 8× FG-1002 only.
- Find your filter size: Check the label on the side of your filter tank — the model number and filter area (sq. ft.) are printed there.
