No any screws. No grounding hole /screw *by on Reviewed in Canada 14 July 2026* great box. But no mounting holes. No any screws. No grounding. Be ready drill them by yourself and find spare screws ### ⭐⭐⭐⭐⭐ Quality. Deep. Flush Punch out. Great option! Warn- no screws! *by on Reviewed in the United States 10 June 2026* I specifically came here to say how good these were.I do have one feedback, or warning, they do not come with the screws for the corners.But, these are good quality (thicker) metal. The cheap ones I bought at HD, were thinner. The HD one was not as deep. Most important. The punch outs on the HD one, stuck in one metal width, the HD punch outs were not flush. THESE PUNCH OUTS ARE FLUSH. You would think that small difference wouldn't matter, but I was doing 2 GFCI breakers. In the other brand...we had issues... The black mark pop making sparking kind when the screws touched the punch outs that were inset.These are thick. Flush punch outs and deeper. I would recommend.I do think the seller could throw in a couple screws. Watch out for that. I only needed 2, so I am a homeowner... I need the screws. ### ⭐⭐⭐⭐⭐ Better than other store prices *by on Reviewed in the United States 23 July 2026* Very durable, best value for the money, cheaper than hardware stores. Nice quality. Not much to expect from a metal square box. But this is the best bang for the buck ## Frequently Bought Together - Hubbell-Raco 239 4 in. Square Plenum Box, Eleven 1/2 and Five 3/4 in.
