Good product but J-Box has poorly stamped perforated exits. Knockout holes are very difficult to remove, causing the box to deform if you try to knock it out. I don't understand the compromise that makes them so difficult to work with. I hope Torchstar reads this and resolves the issue. We have replaced our entire hotel with 6 inch ceiling lights and their boxes are fine. On the other hand, working with them is just a nightmare.
