Hayward KingRay Disc
The Kingray disc is a replacement part that was made by Hayward. The same high-quality materials were used to manufacture the original factory part. Making this a genuine OEM product.
The disc was designed to lead in the fight against dirt, debris, leaves, and algae that litters the surface of your pool year in year out. The disc sweeps up dirt and algae off the surface of the pool kind of like a broom does on the surface of your home (minus the algae). This also moves the debris and dirt towards the bottom center of the KingRay to be sucked up, out, and into your filtration system.
The disc is blue with little fin-like teeth that run along its edge. It also provides greater maneuverability for the cleaner while also creating better sucking power to pull up a larger range of debris and mulch off from the help of the cassette assembly and diaphragm.
