  • 22 inches long Rod length is model specific, so the 36 square foot filter takes this one and larger tanks take longer rods.
  • Listed for DE3600 and DE3620 The 36 square foot models in the Micro-Clear and Pro-Grid families.
  • Holds the grid pack together The rod runs through the grid assembly and keeps the grids clamped in their spacing.
  • A bent rod lets DE through If grids shift out of position the seal at the manifold opens and powder returns to the pool.
  • Change it while the tank is open The rod is only reachable with the grid pack out, so inspect it during the annual grid cleaning.

Product details

The Hayward DEX3600R is the 22 inch retainer rod for the 36 square foot DE filter, listed for the DE3600 and DE3620. It is the genuine Hayward part.

What it does

Inside a DE filter the grids are not loose. They are stacked in a pack held to a fixed spacing, and the retainer rod is what runs through and clamps them. That spacing is what lets each grid seat against the manifold. Once a rod bends, corrodes or loses its threads, the pack goes slack, grids move, and diatomaceous earth starts coming back through the returns into the pool.

When to change it

The rod is buried in the middle of the grid pack, so it only gets looked at when the tank is already open. That makes the annual grid cleaning the moment to check it. If it is bent or the ends are chewed, replace it then rather than closing the tank around a part you already suspect.

Note that the model coverage in the source varies. The part is listed specifically for the DE3600 and DE3620, while the broader Micro-Clear and Pro-Grid families include other tank sizes that take their own rod lengths.

What people ask about this product, answered by our pool techs.

Which filters does this rod fit?
It is listed for the Hayward DE3600 and DE3620, the 36 square foot DE filters.
How long is it?
Twenty two inches. Rod length changes with tank size, so a rod from a larger filter will not seat correctly.

It runs through the DE grid assembly and holds the grids clamped in their correct spacing so they seal at the manifold.
Is this a genuine Hayward part?
Yes. It is Hayward part DEX3600R.
