SamIdea Outdoor Electrical Box Weatherproof, IP67 ABS Plastic Electrical Enclosure with Mounting Plate, Wall Brackets, Weatherproof Hinged Door IP66 Small Project ABS Plastic Case (110x80x70mm)

I had to protect a small charger from the elements. Since the components were electrical, it had to be water proof or at the very least highly water resistant. It's a high quality product that filled the bill perfectly. A final thought: All the components are made of materials that won't rust even in a harsh environment.

This is a decent 5x7 project box. All plastic including the screws that hold the cover on. That means no rust or corrosion but may limit the number of times you can open and close the box without breaking the plastic screws since they need to be torqued down to maintain water integrity. I would have preferred 304 stainless cover screws. I tested for watertightness using a commercial sink high pressure sprayer and it stayed dry inside. It has an inside mounting plate with screws to attach it to the box, but no box mounting hardware and no cable glands to get wires in and out of the box while maintaining integrity. You'll have to buy those elsewhere.

Well.. I havent actually submerged mine in water, but I can tell by the fact that the inner mating surfaces are gasketed; this box is going to keep water OUT, as long as your own wire penetrations are sealed with a proper "cable gland" or other appropriate water-resistant pass-through (such as bulkhead pin connector or similar). The material is a very rigid polymer of some type; meaning it should hold its shape well and remain waterproof over a long span of time, instead of warping/drooping out of shape and allowing the gasket to be defeated. Thats a definite point on the positive quality checklist there. Four plastic outer fasteners ensure that the case can be shut tightly without being chewed up badly by the MUCH-harder option of a steel bolt. Plastic is a better choice in this case. Plastic fasteners also allows for much safer insulating factors when dealing with HIGH VOLTAGE like flyback transformers, HV capacitors, and other things of that sort. Metal fasteners would be likely to attract stray voltage arc flashover. There are actually two small, short metal screws that hold the grid plate to the inside of the casing, but they are isolated inside and dont pose much threat of any manner of arc flashover at all. If you are dealing with very high voltages, you ought to be potting those items in vacuumed epoxy anyways to FULLY isolate their output poles. Simply enclosing them isnt the best idea overall, but thats another story to learn by one's self when they "cross that bridge" one day. This plastic grid board can be built on while outside the box and then screwed in to the casing (both screws are included) once your build is complete and enough room is left behind the grid board to allow component leads, wires, etc to be freely passed around the inside, from front to back or top and bottom. Theres really a hundred different things that could be done with a box like this. You could partially wire up a decent size marine electrical auxiliary system with several relays and fuses, a offroad vehicle lighting power management control junction, or plenty of other things electrical/electronic/etc or even just store your various vehicle keys inside it while protecting them from any moisture damage. You could even store your sandwich in it.. LOL! Nah, I think the igloo cooler would be best for that.This thing is good enough quality and a fair low price, that I suggest you get one if you can find a smart use for it. Im going to make some manner of RF remote interface switch housing for 120v AC appliance of some sort like a ceiling vent fan, probably. Plenty of possibilities. Thumbs up!
