another question for the tech pros on my list

[wendyzski]

I have a client who has a server power cable stretching across an aisle. They are worried about cleaning crews.

I know where to get secure cord covers, but they would also like the be able to "screw the plug to the wall so it can't come out"

Does anyone know of such a product and/or what one mught be called? Googling a variety of phrases didn't help me much.
