Hayward SX242MA2 Sand Filter Folding Lateral Holder Assembly - For S310SX

What This Part Is Used For
The Hayward SX242MA2 is a folding lateral holder assembly used in the Hayward S310SX sand filter as listed. It supports the internal underdrain lateral structure at the bottom of the filter tank. This component lives inside the filter and is accessed during sand service.

Why This Part Matters
If the lateral holder is damaged or not supporting the laterals correctly, the filter can bypass and allow sand or debris to return to the pool. Poor underdrain support can also reduce filtration performance and make backwashing inconsistent. Replacing the holder assembly restores proper underdrain positioning and stability. This is commonly replaced during sand changes when internal parts are exposed.
