These are new open box parts that my massage business had for our electric massage tables. However, they may work for a variety of healthcare tables. We went out of business during Covid. The part number on the units are ECO9F-020MM5AA-000 Please see pictures online of the spec pages that I found online. I also took a picture of the plug close up. I believe these items are new, but to be safe, I have stated that they are used. The date of manufacturer ranges from 2016 to 2019.
