Product details
The Pentair R01052 is the lock screw for the Rainbow automatic feeder, models 320 and 322. It is the genuine Pentair part.
What it does
The lock screw holds the feeder setting where you set it. Without it, adjustments drift and the feeder stops doing the one job it was installed for.
Why they fail
Feeder hardware lives surrounded by chlorine. Screws corrode, threads strip, and small parts go missing during a service call. It is a cheap enough part to keep one on hand rather than lose a feeder to it.
