I concur with Joey D. All of the Raco and Steel City 1 gang and gangable device boxes I have in stock are missing the GND marking completely. Only the Raco 232 4x4 boxes with the raised dimple with a tapped hole say GND. I checked Raco 590, 390, 601 and 605. I also checked Raco 145 octagon box with RX clamps. No GND stamp. Now what?
