## Questions & Answers

**Q: s there  rear knock out in the box for a twin and earth cable, I wasn't sure if the clip section of the back plate would make this impossible.**
A: as far as I can remember no all the cable entries are on the sides

**Q: I have a cctv system that uses bnc connectors. will these fit through the cable entries?**
A: Mal, I have only used these for connecting the wiring on outside lights with standard power cable.  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.

### ⭐⭐⭐⭐⭐ Would recommend for DIYer
*by  on Reviewed in the United Kingdom 14 September 2025*

Simple to install and has kept all traces of moisture and all foreign objects out. Would buy again.

### ⭐⭐⭐⭐ Good connection box, but one minor design flaw
*by  on Reviewed in the United Kingdom 20 May 2021*

Very good box, I used it to install an outside light. The internal connections design allowed for simple quick installation. My only criticism is that the self sealing rubber entry on the box is recessed, which allows water to collect in it. As the cable I used was via the top entry, I am hoping that this does not cause a problem in the future, as I noticed it pooling in there when I later adjusted the lamp settings. Time will tell. I may have to fill it some time with silicone filler to ensure safety.
