Need a heavy duty receptacle

Most,not all, hospital grade receptacles provide a tight grip, that's what they're designed to do. If you want to get a bit more performance, give Porter Ports a try.

Hi Markpao

What power cords are you using where their bulk is causing it to back out of the receptacles you have?

I use the Porter Ports both old and new in my system and they firmly grip the 12AWG power cords I have.

The PS Audio Decora Style receptacle has held some of the 12AWG power cords I have too.

Jedinite24,
I have 2 Custom Power Cord Company model Eleven's for my subs. Believe it or not the bigger problem is my Silver Circle Vesuvious plugged into a PS Audio Soloist wall outlet for all my other components. The Vesuvious is lighter and smaller, but backs out of the outlet easier. Hate to ditch the Soloist, but don't know what else to do.

I also recommend the Porter Ports. Excellent for the money!

I like the Jenna Labs cyroed outlet.
