Masterplug Weatherproof Electric Box for Outdoors, 345 x 220 x 126.5 mm, Green

Works well if used properly. Really simple to use provided you respect its limits and use it responsibly. Used over Christmas as a junction box to put an old extension lead in. Plenty of room for transformers plugged into a 4g splitter and the sturdy plastic construction and decent seals have kept it bone dry over the last 5 weeks. Top product, bargain.

Ideal for my need as used on my outdoor garden bar. Very reasonably priced, and well made.

Does what it should An excellent waterproof box for outside. Has kept the extension and plugs completely dry

Strong weatherproof box with good size and easy to operate locking handle.

Absolutely perfect for the job. Great seals and easy to connect the plugs and close it.

Just the same like a B&Q only much cheaper. Sturdy and good quality

The Masterplug WBX-MS has quickly become a staple in my garden and outdoor setup. It’s one of those “buy once, use for years” pieces of kit — simple but built to do its job well. ✅ Why it works so well: • Truly weatherproof – After weeks of rain (UK-style drizzle and full-on downpours), not a single drop made it inside. The seals are tight and the clamping lid locks down firmly. • Good internal space – Easily fits a chunky plug extension and multiple adapters without it feeling cramped. There’s also room to run cables cleanly out the bottom while still sealing the lid. • Versatile mounting – It’s easy to secure to a wall, fence post, or even use freestanding if needed. • Great for temporary setups – Perfect for Christmas lights, patio heaters, outdoor entertainment gear, or a pond pump. 🛠️ What to be aware of: • Lid can be a bit stiff at first – But it softens up with use. That stiffness is probably what keeps the weather out! • Check your plug sizes – Very large timers or awkward plug designs might be a tight fit (though most standard ones are fine). 💬 Final thoughts: If you need a reliable, no-fuss weatherproof box for outdoor electrics, this one does the job excellently. Feels solid, protects well, and is more spacious than it looks at first glance. I’d confidently recommend it for both permanent installs and seasonal use.

I already had one of these and needed another one. Works great and is a great buy and well priced.

It’s a bit pricy, but it’s worth it. It offered the best protection for my LED light drivers in an outdoor lighting system.

tiny pin that holds one off the 2 hinges came off which made the box not weatherproof, the pin is extremally tiny and I was not able to locate it
