Need a heavy duty receptacle

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?

Yes. I love amplifiers and vintage gear so mono-blocks and bi-amping leaves me with a load of power cords that can be tweaked. They tend to be spendy purchased so I make them with off the shelf parts. These guys take it a bit farther than I do but what the hay? http://www.carveraudio.com/phpBB3/viewtopic.php?f=39&t=11564&start=0
Same electric supply should have "safety cable" that will hold plugs into outlets. I have seen theses in pro audio applications.

Markpao,

Just curious.... Did you install the receptacles with the equipment ground up?
.

Yeah, I tried that way first. Then turned it around after I saw it backed out just the same. I think now after spending more time with this, that the problem is more to the fact that the power cords are so stiff, than the actual weight of them. Like I mentioned, I have them molded so the floor actually supports them and keeps them fully plugged in now.
Thanks for all your help.

Hey Markpao

I can't find the thread but there was an A'gon member here who used fishing line to help support his beefier power cords. Another gent I met used really thick pipe insulation to help support his power cords so they wouldn't slip from the receptacle. He measured the distance from the floor to the outlet cords, cut the pipe insulation and put it right under to prop it up. Since the outlets were behind his gear no one could see the propped up cords.

I'm curious too about 3 or 4 prong power cords and the special receptacles they require. I see this kind of cord and outlet with servers and dryers. Since there is a market for these big and beefy power cords in the audio community why it hasn't been attempted to use these types of locking receptacles etc etc.
