IP68 Waterproof Junction Box, 2-Way Outdoor Cable Connectors with 2 Cable M20 Gland Wire Connector Electrical Junction Box for 5-15MM Diameter Cable, Black

If you are running power outdoors for garden lighting, floodlights, or external tech, a completely reliable weatherproof connection is essential. This Elezenioc IP68 junction box is an absolute hidden gem. It is incredibly well-engineered, easy to work with, and priced exceptionally well for the level of protection it offers. Weatherproofing & Seal Quality: The IP68 rating on this box isn't just for show—the build quality genuinely backs it up. The main housing features a robust rubber seal that compresses beautifully when the lid is screwed down, creating a completely watertight and dustproof enclosure. Once closed up tightly, you can have total confidence leaving this exposed to heavy rain, snow, or damp garden conditions. Adjustable O-Rings & Installation: One of the best design choices here is the inclusion of multiple sizes of internal rubber O-rings (glands). This makes a massive difference during installation because it allows you to adapt the entry points to the exact thickness of your cable (from 5mm up to 15mm). Instead of fighting to get a tight fit or worrying about gaps, you just select the matching ring, slide the cable through, and tighten the M20 gland. It clamps down perfectly, creating a rock-solid, strain-relieved, and secure seal around the wire. Ease of Use & Value: The internal 3-pin connector terminal block makes the actual wiring straightforward and fast. Everything fits neatly into the compact PC plastic housing without having to dangerously cram wires together. At under £7, the price point is unbeatable for this level of durability and ease of installation. Should you buy it? For anyone tackling a DIY outdoor electrical project, this junction box takes all the stress out of weatherproofing. It’s cheap, incredibly versatile due to the adjustable gland inserts, and seals up like a vault. An easy 5-star recommendation!

Good for 30 amps or below

A nice little cable connection box that is waterproof (and also meant to be suitable for full immersion) & simple, if a bit fiddly for larger hands. I would recommend this product as it is very reasonable priced & suitable to be fixed on place via external lugs. As usual, the screws that fix the lid down (4 No, one in each corner) could be better quality but easily swapped out if necessary.

Well, isn’t this a delightful surprise! This waterproof junction box is the HMS Victory of electrical enclosures, ready to sail through any storm with the grace of Admiral Nelson himself. As someone more skilled at brewing tea than handling tools, I found installing this box to be easier than avoiding eye contact on the Tube. It’s so watertight, I’m convinced it could survive a dip in the North Sea. I tested it in the rain (because, let’s be real, that’s a typical British weekend), and it remained drier than the Queen’s humor. The build quality is top-notch. It’s sturdier than a cricket bat and just as satisfying to handle. I’m pretty sure it could withstand a monsoon, a flood, and maybe even the aftermath of a particularly rowdy pub quiz. In short, this junction box is the answer to all your waterproofing prayers. If you need a reliable, no-nonsense solution that laughs in the face of British weather, look no further. Cheers to dry connections and no more electrical mishaps! 💧🔧🏴

Overall this 𝐈𝐏𝟔𝟖 𝐖𝐚𝐭𝐞𝐫𝐩𝐫𝐨𝐨𝐟 𝐉𝐮𝐧𝐜𝐭𝐢𝐨𝐧 𝐁𝐨𝐱 seems well built and the seals appear adequate for the purpose I required it for. However, as this is a product that requires substantial use prior to writing a review to provide a valid assessment of the the feature we all would have purchased it for, i.e. Endurance; it's impossible to say much regarding that and as such, the following should be taken with consideration of this: In the week I've had it, there are no signs of possible water ingress or any signs of seal failure. Whether this will remain the case 6 months down the line, who knows. That being said, as a result of an old technique I was taught, which has now become habbit; I also applied some silicone sealant around the ends of my wire cables before sliding up the yellow waterproof rubber rings and screwing on the black plastic jackets. Did I need to do this... probably not, but it wasn't going to be detrimental either, as the box will hopefully never need to be removed within at least my lifetime. 1 year on and still working fine, with no signs of weather damage.

Pleased with the junction box

I found that outside security lights now seem to come with a cable that is already secured to the light and require a junction box to connect to the mains power supply. Leaving a loop of cable beneath the light and junction box ensures any drops of water collect on the cable and are less likely to find their way into the electrical connections. This junction box has a good selection of grommets and a simple connection block inside. Screwing the outside nut clamps the cables nicely. My only gripe was that the holes provided for the small screws securing the cover were too small and I had to drill them out a bit, otherwise I could not tighten the screws properly. Perhaps the manufacturer could remedy this but having got it all installed, I didn't follow up.

I bought this to connect two outdoor security lights. It's just what you need, easy to use with a screwdriver and can be used outdoors with its IP rating. I would recommend this item.
