Okay, first off, the cutouts are 3/4" not 1". (Probably the metric equivalent, so don't buy 1" cable glands because they won't fit at all!) After inspecting the rubber covers on the knockout holes, a utility knife is all it takes to make the appropriate cut so the glands really aren't needed Secondly I was hoping for a more decent plastic as it seems a bit cheap Use this box as a junction box for outdoor IP zip/category 6 connectors of CCTV cameras I think it will work That is all I have for this review.
