Review: Very nice quality box- substituted for old-work, cut in...worked perfect - Very durable boxes, hard type plastic that isn't brittle. Rigid, durable boxes with plenty of interior room. Wire knockouts knock out easily and don't leave sharp edges to cut into romex and wire insulation like some of the other brand boxes are notorious for. Love the mounting means for the box. I could not locate a 5 gang cut-in box for old work anywhere online. Purchased this box with the sole purpose of modifying. Worked perfect with a little modification. Cut the mounting tabs off and was able to utilize this one to serve as an old-work box. The forward angular screw landings served me well. Furthermore, the tapped holes for the device screws are durable as well. These sections don't strip out like some of the other boxes on the market. Just a very nice, quality box.
