The Waterway Square Spa Skimmer Weir Door with Foam is a replacement skimmer component for compatible square spa skimmer assemblies. The weir door helps improve surface skimming by controlling water movement into the skimmer opening, while the foam helps the door float and respond properly as water level and flow conditions change. A damaged or missing weir can reduce skimming efficiency and allow debris to drift back into the spa.
Replace this part when the original weir door is cracked, warped, waterlogged, missing, or no longer moving freely. Match the square skimmer style, door size, hinge points, and part number before ordering to ensure the door seats correctly in the skimmer body.

- Foam insert helps support proper floating action
