Where can I get a open end wrench power tool?

I'm trying to visualize how that would work. I'm pretty sure they are not made. Homer Simpson invented an electric hammer, though.

They don't exist, and there is ABSOLUTELY ZERO reason to make one.
It is physically impossible for an open end wrench to be useful where a power tool would be helpful.

You will not find one. If you can use a socket, use one. If not, use a ratchet wrench.

Home Depot?
