looked everywhere for this particular unique knob, then realized Intermatic had a store with all the parts. Thanks for having this Store set up!

Perfect Fit
From Jon Kahner of San Antonio, Texas on 9/26/2019.

These knobs are the exact replacement knobs for the Intermatic timers at the hospital project I'm working on. They go on very snugly, so there's no chance they will "accidentally" fall off nor will they strip. Thank you, Intermatic.
