We had lost one so I ordered this as replacement. Works well with our pump timer.

I received these little knobs for the pool timer. They went on instantly it was easy installation. The quality is excellent and I got a good value for my money. Love these

Exactly the parts I needed so set up pool pump/salt cell running in the morning and in the evening. Only took a few minutes to install. Now the chlorine generated in the evening can do it’s work before being decomposed by the sun next day.

Timer that controls outdoor building lights malfunctioned. Tightened the "ON" clip but it wouldn't stay on dial stronglyenough to trip timer. Ordered these, easy install, works perfectly. I saved the old ones...I think the screws just need to have the point sharpened to grab the dial wheel better.
