Review: A super quality junction box, eminently fit for purpose - A very good quality, rugged junction box at a great price, with all you need for space and weatherproof sealing, the cover is sealed by compressible rubber gasket, as you'd expect. However, it also comes with soft rubber caps that seal the heads of your base fixing screws inside the box. This prevents run-down and water ingress from the rear, as well as electrically insulating the screw heads. Lots of room internally without added clutter, permitting your size and choice of termination. Furthermore, the cable entry points are not the cheaper permanent break-out types of cheaper boxes, but are actually tightly-fitted plastic plugs than can simply be knocked out for rubber cable seals or glands. This makes things so much easier with a pre-installed/pre-wired box should you wish to run in additional cables in-situ at a later date, or even remove/reposition cables and plug the open holes off. Just leave the caps inside the box so you never lose them. A super quality product I would buy again without reservation.

## Questions & Answers

**Q: I need an outdoor junction box for 12.9mm armoured cable.  I see that the holes on this are M20; is there space to drill out to M22?**
A: Hi, thank you for your product enquiry.The knock-outs are 20mm diameter as standard but also have provision to be drilled out to a maximum size of 25mm, so they would be suitable for your requirements.

**Q: Are there terminal/conection points inside this junction box, Could really do with a picture of what's inside really.**
A: Yes, there are terminal connectors inside the box.  They are comprised of a (loose) strip of ordinary insulated connectors. It all works, 'though I would have preferred the connectors secured to the base of the box, like a junction box.

**Q: For the junction box if a cable comes in through the back how do I make it waterproof for water running down the wall?**
A: You can buy a  Wiring Grommet Rubber  https://www.amazon.co.uk/FIXMAN-255645-Rubber-Grommets-35pce/dp/B01MA6T2HD/ref=alp_dpwidget_a_w_?th=1&psc=1&smid=A3P5ROKL5A1OLE If you search enough you can  buy individual.  I would suggest you also use a circle of sealant around the box for extra precaution.

**Q: What is the size of the recess to the lid? I want to mount a cctv camera with a 70mm dia base. The box will house the cables.**
A: It should say in description ?

### ⭐⭐⭐⭐⭐ Well-Made and Robust Junction Box
*by T***H on 19 June 2025*

Excellent product - robust and water tight. Good instructions. Feels well made.

### ⭐⭐⭐⭐ Different brand supplied, but very good for the price.
*by A***R on 1 November 2020*

The box itself is very good, decent quality plastic, press-out knockouts (the one on the back is drill-out but that's fair), shrouded drain holes, grommets supplied for all fixing entries. It doesn't come with glands, but if you expected it to you should probably have called a sparky to do the job for you (especially as plenty of outdoor electrical jobs are in-scope for Part P). That said, the box I recieved was supplied with Masterplug rather than British General branding. BG and Masterplug are part of the same company/group, but in my experience the BG branded items are very high quality and mostly sold by trade suppliers, whereas Masterplug is the brand you'd find on the cheapest made-in-China extension lead in the Tesco homeware aisle. If I'd have known this, I might have shopped around first. All in it's great for the price, but the branding is worth bearing in mind if you were going to pay a premium for British General.
