You know open frame devices like generators or air compressors often have… where there’s metal frame around the unit. And very often there’s some sort of rubber protector/feet on the bottom of the frame to protect floors and dampen vibration and such.
Do they make those protectors separately? Or, if not, any suggestions on what works well? Just cut a rubber tube or something and slip it over? I found a spiral “hose protector” which might work to wrap around.
