Hayward Lateral Assembly (S310S), SX242MA2

The Hayward SX242MA2 is the folding umbrella lateral assembly for the S310S sand filter, covering filters built from 1999 to the present. It is the genuine Hayward part.

What the laterals do

The laterals sit at the bottom of the tank under the sand bed and collect filtered water while holding the sand back. When one cracks, sand starts coming back into the pool and flow through the bed goes uneven, so the filter stops doing its job even though everything else looks fine.

What is in the box

This is the complete lateral assembly, supplied as one piece rather than as individual arms. The plastic air tube, Hayward SX200Z1, is a separate part and is not included, so add it to the order if yours is damaged or missing.

Before you order

Check the build date of the filter. This assembly covers the S310S from 1999 onward.
