Questions about this item
How do I install the Dayton switch knob on the 2RDZ2A model, and what step is commonly missed?
Push the knob onto the switch shaft until it seats fully; the step often missed is verifying the knob's indicator aligns with the switch positions before tightening any set screw.
What maintenance or replacement will this Dayton switch knob need over time?
The knob itself requires no scheduled maintenance; replace it only if the plastic cracks, the fit loosens on the shaft, or the indicator markings wear off.
