From the Inspector side of me although they're not part of the permanent wiring.The UL listing for them is not for use as a ground lift but for a half hearted attempt at providing an equipment ground when one is not avaiable ie two pronged receptacle. Older electrical systems, before romex, very often were done with metal clad cable and metal boxes. The yoke of the recpt. was grounded to the box and thus the cable and thus the service grounded conductor ( neutral). By using one of these adapters and running the cover plate screw through the little thingy at the base of the adapter you've provide somewhat of a grounding connection. Not a great one.



All of which only serves to confuse the issue here.

I hope the poor fellow does not take this to mean that he is supposed to put a screw on the adaptor and thus return the lifted ground now...
