Porter Ports are installed, but have to report that they don't hold the power cords any better than the outlets I replaced. I did manage to "form" the power cords (they are stiff!) so that they are resting on the floor, which now picks up most of the weight of them. It'll work unless someone hits one with the vacuum.
Don't get me wrong, the Porter Ports are far superior in quality than the cheap outlets I replaced, and I probably would have replaced them anyway.
Jonoulman,
I'm aware of the twist lock plugs and outlets in the electrical supply stores. I would imagine you had to make a DIY power cord?
