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 J***D on 27 April 2026* Great quality, perfect for an outdoor connection for the new summer house.
