Review on Zulkit Waterproof Plastic Project Box ABS IP65 Electrical Junction Box Enclosure Black 6.22 X 3.54 X 2.36 Inch (158 X 90 X 60Mm) by Robert Blanton

installed the gasket. installed and tighten the 4 screws. 1 corner of this box was lifted and not sealed.removed screws and turned the top. installed 4 screws and tighten. same thing 1 end was not sealed. removed screws and gasket then put top back on with the 4 screws and tighten. 1 corner raised up with no effort about 1/8" . I ordered 2 of these so I checked the second one. Guess what. same thing.Got longer bolts to tighten from very top of box. Discovered that 1 of the thrd. inserts in the box is not taped all the way through. 1 bolt will only thrd in about 5 turns and the other 3 will bottom out. Again both boxes are same way. also discovered another issue. after the top is tight with gasket installed the lid is not completely sealed in the center.
