2 Pack Black Waterproof Plastic Project Box ABS IP65 Electronic Junction Box Enclosure 3.94 x 2.68 x 1.97 inch (100 x 68 x 50 mm)

Caixa em ABS de muita qualidade, material muito bom mesmo.

I think I've bought like 16 of these at this point, I keep using them and buying more. The boxes are super sturdy, like you could JUMP on them and not damage them. Thick walled ABS, LONG stainless screws, beefy brass inserts for the screws, surrounded by thick plastic framing. It's all very high quality and yet at a low price.I always have to make some holes in them, and I use a side-cutters, flush cutter, and x-acto knife, as well as pre-drilling holes on the bench drill. The plastic machines well - I've never seen one crack, chip, or split, and I've seen those problems on a lot of other plastic boxes in the past. The plastic is strong but just soft enough to machine easily.The boxes come with a length of white spongy gasket that you have to stuff into the groove on the box, and then cut to length and stuff in the last end. It takes a little time, but it's not a big deal, and makes the box completely waterproof. I've had mine rained on many times without problems. Hot glue sticks well to it also, and I use that as part of my waterproofing of my connectors and displays.In my reviews I try to point out a weak point of the product, even if all I can find is something very minor, but these.... there really isn't *anything* I can think of that I'd change. They're simply perfect for what they do, which is pretty rare to see nowadays.

Used in a DIY etching machine and it works well. Very sturdy and well made

TL;DR - I've bought 2 of these for homemade music equipment, both turned out great!I use the large boxes (200mm by 120mm by 75mm, black) for DIY electronics projects. Here are the my key takeaways.Good qualities:- The material is easy to drill holes in.- The thickness is perfect for mounting most components (switches, LEDs, potentiometers, power connectors, MIDI connectors, audio jacks, and more)- The nuts that are built into the case for the top are metal and don't wear out if you need to open it repeatedly- Box is very sturdy- The large box has enough space inside for most DIY electronics components, including commonly found PCB boards. (from photo, notice that the PCBs are standing upright and fit without issues)Bad qualities:- The internal standoffs aren't very useful, and get in the way. But they can be snapped off.- The lid is slightly curved, and the curve gets worse if you use the waterproofing seal. It would have been great if the case had 6 screws instead of 4- The outer surfaces easily scratch (from fingernails or tools). Handle carefully!Recommendations:- I use DeWalt titanium drill bits and a conventional hand drill to make holes.- Use a small drill bit to make a guide hole first before making the larger hole.- After drill, the edges of the holes/cuts tend to be jagged, I recommend using washers or component mounts with a flange to cover the imperfections. (From the photo, notice the mounts for the LEDs).- The internal standoffs can easily be snapped off using large pliers.- Simple rubber friction feet work great for preventing it from moving around if sitting on a smooth surface- Unless you need water proofing, I do not recommend using the waterproof seal. It causes the lid to curve when screwed in. The lid is perfectly snug without it.I've purchased other boxes of different dimensions from the same supplier. The smaller boxes DO NOT exhibit the same curving issue with the lid. Even then, I still give the box 5 stars as the curve is not really noticeable at a distance, and does not effect its use if you are not putting other devices on top.

Good Dirt Cheap solution and it worked very well for what I used it for. It does not measure out perfectly to the dimensions listed but close enough for what I was doing. I did not test the water proofing but I would honestly not trust this box to be water proof. (to be fair I did not need it to be waterproof so I was not concerned with that). It is not UL rated and the plastic is a bit on the cheap side but it is good for some projects. In my case low voltage, low current 12v DC switch box that is used indoors in a dry location. Buy with confidence just understand what you are buying. This is not a high end electrical box and it is priced accordingly. If you need a low cost box for a simple, low voltage, indoor, light duty project this is for you. If you are looking for more quality you will need to pay more for a actual name brand.
