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.

I needed to extend an outdoor power cord on a pond filter so, having read many different reviews, I decided to give this Elezenioc IP68 Waterproof Junction Box a try. I'm no electrician (female in her 50s) but I managed to work it out, without instructions. The rubber bung parts are excellent and really do tighten up around the cable to make a water tight seal. The "lid" goes on well too and the little seal around the edge seems like it's up to the job too. My only gripe is the little white connector inside. It was very fiddly and, in the end, I ended up pulling both ends of cable right out through the box, wiring into the connector then carefully pulling the connected wires back down into the box. I'm sure the "clip lock" type fixings available on connectors would have made this a much easier task. But.... that said.... it's done, it works perfectly and my pond pump is working perfectly. I think, if I ever had to use a similar product again, that I'd look for one with an easier clip type connector method, simply for ease of use. Other than that, good item. Does it's job!

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.

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.

The item does exactly what it says on the tin They are easy to use and work well and installation is easy I have even bought an extra one, as I needed it. I would definitely buy another one and highly recommend They are great and look good as well
