Way back when I was involved with wiring devices, Leviton was the king
of residential devices or as is was known the strip & stuff line.

Hubbell was king of the high end devices.

You want high end devices, look for 5262 with is an industrial device,
5252 which is a commercial grade or if money is no object 8300 which
is hospital grade.

Probably won't find any of them at a DIY center.

The "spec grade" outlets are available at HD and their ilk. Cost is a couple
bucks each versus the $0.50 for the cheap junk.

Some brands (Eagle IIRC), has the back clamp capability in the spec grade.

The nice thing is that the device manufactures have produced most of the
styles in the spec grade so you don't have to stay with Hubble brown if you
want a decent outlet.
