ECN Forum Forums Photo Discussion Forums Electrical Nostalgia Which Came First?

I have a couple of identical electrical plugs at home in my collection. One is labelled Leviton on the pins. The other is labelled Snap It.

I believe Snap-it used to be a separate company. Now it's a Leviton trade name. They still label their round rubber plugs with the Snap-it "S" on the front cover.
