However, I have a spare JB and a BNC plug, and an inquisitive mind! So I cut out the rubber seal with a Stanley knife and the BNC plug will almost, but not quite fit through the hole. If I was doing the job I'd be happy enough to then file the hole a bit bigger so the plug fits through. However, having removed the rubber seal you'd have to use an additional gland to seal the cable entry if it's for outside use. Hope this helps. **Q: Need some help whats the internal measurement measurement in MM** A: There are screws in the corners **Q: are the boxes ok for cctv cable connection** A: The terminals inside are for mains electric - 3 screw type terminals. If using a coax cable or ethernet for the CCTV you could bypass the existing terminals and use a coax connector or ethernet connector inside the box. I was impressed with the box - it is simple and robust and the self sealing glands are excellent. The build of the box suggests that it would be weatherproof. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality and functionality *by on Reviewed in the United Kingdom 27 April 2026* Great quality, perfect for an outdoor connection for the new summer house. Easy to use and lots of useful connection points. Simple look to fit in with others. Easy to install. Compact design with plenty of room for connections. ### ⭐⭐⭐⭐⭐ Junction box *by on Reviewed in the United Kingdom 16 February 2026* Perfect for the job I had to complete ### ⭐⭐⭐⭐ A bit tight for space inside *by on Reviewed in the United Kingdom 13 October 2021* I'm a keen DIY-er so managed to use this, although in hindsight, I'd have gone for a box that is slightly larger inside.Pros:1. Strong plastic construction that I don't think will crack.2. Front 4 screws seal the front of the unit nicely.3. Comes with a connector block inside.Cons:1. There was only just enough space inside the connector box to connect my 6mm SWA cable to the cable going through my wall. In making the connections, I could not seat the connector block onto the slots where it should really go within the unit, but I could have it "loose" inside and seal the front of the unit properly.2. I'm not confident about the waterproofness of the rear of the unit, even with a suitable grommet, hence the black sealant in the photo (which I wish I hadn't done because it's a bit untidy). ## Frequently Bought Together - Wiska Combi 308/5 - Black Waterproof Junction Box With 5 Pole 4.0mmsq Screw Terminal & 8 Self Sealing Cable Inlets (IP66 32A L:85x W:85x D:51mm) - 10 Pack M20 20mm IP68 Waterproof Black Cable Glands, Suitable for 6mm - 12mm Cables, Plastic Nylon Compression Glands Connectors with Locknut and Washer - AVARTEK - WISKA Box Combi 206 Black Empty IP66 Weatherproof Outdoor External Junction Box --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/53142737-combi-308-5-black-waterproof-junction-box-with-5-pole](https://www.desertcart.no/products/53142737-combi-308-5-black-waterproof-junction-box-with-5-pole) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-10-06*
