The URL to the 14 AWG is above. I think rockler has a 12 AWG version as well.
I have an old Sears 12 AWG one, that had a light on it. I cut it off and installed a leviton commercial outlet on it.
You can see it off to the left side in this picture, it is in the center of the garage ( front to rear and side to side )
I went 12 AWG, as it is in a 20 A outlet / circuit. Figure if I am using something that has a high current inrush on start up, I'm better with the 12 AWG.
