RACO 4 in. Square Plenum Box, Drawn, Airtight, 2-1/8 in. Deep, Gray

great box. But no mounting holes. No any screws. No grounding. Be ready drill them by yourself and find spare screws

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.

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

Being that they're plenum boxes, I'm not going to complain about the lack of mounting holes. However they really should have included 8-32s as even the cheapest 4s boxes usually do. They worked great with raised covers and since they have rounded edges they look better than the perfectly square ones sold locally.

This is a well built junction box, however it does not come with screws, no threaded ground screw, and no attachment holes. Not a choice for someone that's installing 25. I only had for to instal four, so not a problem. I had screws that fit and I drilled four mounting holes along with a ground mount which I drilled and tapped to a #10 green ground screw. I was going to give this four stars but because this box is so robustI had to give this five stars. This is actually industrial grade, thick and heavy.
