Masterplug WBX-MS Weatherproof Electric Box for Outdoors, 345 x 220 x 126.5 mm, Grey

The Masterplug WBX-MS Weatherproof Electric Box has been an absolute lifesaver for managing outdoor electrical gear. We’ve got a few outdoor appliances and lights that need a safe power source, and this box provides just that. It’s sturdy, well-built, and exactly what we needed to keep everything protected from the elements.The size is just right—not too big but spacious enough to fit a multi-plug adapter and a few cables comfortably. I love that it’s weatherproof, which means I can leave it outside without worrying about it getting damaged by rain or dust. It’s been through some wet weather and still looks and works great, which gives me peace of mind.The grey colour blends nicely with the surroundings, so it doesn’t stand out too much, and the lid closes securely, ensuring that no moisture or dirt gets inside. The box is also easy to set up, and the internal space is well-designed, making it simple to organise cables and plugs neatly.Overall, this weatherproof electric box has been incredibly useful for my outdoor power needs. It’s reliable, durable, and does exactly what it promises. I’d definitely recommend it if you need a safe and convenient solution for outdoor electrical equipment.

Well made Great price. Made putting the Christmas decorations outside a much easier task. I was that impressed I bought another one. Loads of cable so could move it around the garden. The box itself was large enough to fit those awkward shaped plugs and it was also waterproof with a nice tight fitting lid.Great product definitely recommend.

This is the best outdoors box out that I have found out there so far. I already have 6 that I've bought over the years as I keep buying more for their good quality .... BUT they are not very high in the inside so you need to understand this if your plugs have different shapes (for example, if you have plugs going LEFT, others going RIGHT and other ones going UP... it might mess up your box not being able to close the lid... so you'll need to have one box per "direction" of the plug... another thing that it is a little bit annyoing is the closing clasp... although the box is VERY secure and keeps the weather out of your leads (trust me, I live in Ireland and we get a lot os nasty weather here) but sometimes it's annoying to close that clasp... the trick is to make sure all 4 corners are fully aligned before you close glasp, then it's easy to close it.

Box works fine although wiring entries are fiddly. Mind you, they have to be watertight so that explains things. I've bought two units in Dec, 2024 to augment the two other exactly similar units bought some years ago. The older units are showing signs of wear and the box upper and base are not sealing tightly so, for this season, I've used aluminium foil self adhesive tape to seal the edges. This is not 8ntended as a criticism!Some observations1. The boxes are not intended as a permanent solution2. Biggest problem in use comes from the accessories attached. Different Christmas lights come with very different plug/transformers. Some have a transformer in line, others have a 90° turn. Having to use a mixture of these can overfill the box. This may well be the reason that the older units are showing signs of strain ...Would I buy more? I just have, and will probably buy another two for use next Christmas.They work well, and are robust. Space is adequate to take a 4 plug extension but maybe compromised by the style of plug/transformers being added. Not a problem with the box!Value for money? Certainly

Have about 5 or six of these boxes now over the past few years. really great a Christmas time for outdoor lights/decorations. Big enough to hold the plug/transformer for the low voltage led lights.Easy to access and watertight so far issues with water getting in

This is a fantastic outside box and extension would definitely buy again.

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.

This is my second purchase. Very useful for having power in the garden. The quality is fine for the money.
