Industrial standard useful enclosure (that's a box)
Really useful small plastic boxes for electronics projects they are made from ABS plastic or similar which is easy to drill or even saw (with a small hacksaw) if need be. The moulding is good quality with little or no flash and they have the familiar "mounting holes and lid screws outside the seal" arrangement so that waterproofing should be good. A soft rubber gasket strip and screws are provided. The screws go into threaded metal inserts that are moulded in, so repeated access would not wear or strip them. Some shallow mounting lugs are also moulded in, they were almost the right spacing for my use but a small metal plate could be used if not. Altogether a good quality neat little enclosure for projects or any other use. You could say, "industrial standard".

Good.
A nice enclosure made of material that can be drilled and machined without cracking as some material does. The effectiveness of the waterproofing is as yet unknown but the sealing strip seems good when cut to length and you can feel it compress when you tighten the lid down, so it probably works!

Solid but not cheap
Expensive for an empty box, but that seems to be the going rate. It seems good quality but will require cutting and drilling for my requirements (power supply)

Compact and Reliable Waterproof Box
The Therlan Waterproof Plastic Junction Box has been a great find for organising and protecting small electronic projects. Its compact size is perfect for my needs, and the IP65 rating gives me complete peace of mind when using it outdoors. I recently used it to house some wiring for a garden lighting setup, and it’s held up beautifully against rain and damp conditions. The material feels sturdy and durable, and the grey-white colour gives it a clean, professional look. The box seals tightly, and the waterproofing is excellent—it’s reassuring to know the components inside are fully protected. The size is just right for smaller projects without being bulky, but if you’re working with larger setups, you might need to go for a bigger option. Installing everything was straightforward, and the box is easy to work with thanks to its solid design. This enclosure is a practical, cost-effective solution for anyone needing to keep their electronics safe from the elements. I’d definitely recommend it for small-scale projects where reliability is key.

Good box, poor QA.
Right size, foam stripping is nice for weatherproofing. One box arrived with one screw in one hole, and 4 loose inside, the other had no screws at all.
