First I ordered a set with two x 2.68 x 1.97 is pretty good. I would definitely give it 4 or maybe even 5 stars. I later ordered 6.22 x 3.54 x 2.36 inches. Well, this one isn't made out of the same material as the smaller box. Plastic is thinner and less flexible. The junction box comes without holes, so I had to drill the holes I needed (what's the use of an electrical junction box if you can't get the electrical cord?) Careful (really thorough) drilling just broke the box. parts. It splintered at the first hole, which would probably prevent a good seal at cable entries. it fell to pieces on the second hole. Quality is not consistent across this family of products and it was probably a stroke of luck to get a better product like the few smaller boxes I got.
