Glenn,

Thanks for raising the point about 314.17(C). This got me to look up the catalog for the box that, to my eye, is shown in Sparky's photo's above. I believe he shows [b][i]Pass & Seymour Slater boxes[/i][/b]

I've been using this line of boxes myself for a few years. Their marketing of the boxes for the built in "Auto/Clamp®" feature sold me on them (along with other features). The single gang wall cases have the feature, but I note in the catalog page linked above, that P&S calls these "Quick?Entry®". [Linked Image]

The single gang "Quick/Entry" has behaved like a clamp for me but I see that it is not manufactured as such by P&S.

I learned (yet another) something today.
