I've seen these for decora style outlets and with different wrapping configurations but none were “perfect” for me.
This fits typical duplex outlets and the “wrap” part just covers regular wall (that's what's pictured). Mounts with the normal wall plate screw. It happens to also be the correct size to cover a double-gang box if for some reason you have a double-gang with only a single outlet in it.
Mounts in either orientation (wraps to the left or right).
Obviously not UL rated etc…
The author marked this model as their own original creation.
