Review: Good quality product - I don't always write reviews but I felt this product deserved it. I normally use the cheaper grey coloured IP rated junction boxes but was looking for something black to match my gates fittings and there is not a great deal of options within a reasonable range. The bottom line I was impressed,easy to remove cover (simple locking screws) rather than the fiddly lever it off type, robust, comes with terminal block that sits nicely in the box and also a fixing bracket for easy fitting / removal though can still use the traditional fixing method - screws in each corner. Cant really fault it and and for a good price as well.
Review: Waterproof, easy install boxes - Bought these for a CCTV project I did. Cameras were easily mounted onto the box as well as the boxes themselves to a hard exterior wall. Even with the heavy rain we we've experienced recently these boxes seem to be holding up really well! If you're really concerned about water tightness then you could always add a dab of silicone, but in my opinion and experience this isn't needed. Great value for money and half the price of others for what seems to be great quality. All round happy!

## Questions & Answers

**Q: Is this product suitable for 2.5mm flexible cable?**
A: I have used 1.5 mm in mine but there is plenty of room for 2.5 and larger cable in there.

**Q: I need to splice two cables together. Which connector post goes with which wire since there are five posts and I have 6 wires?**
A: You shouldn't attempt to work with mains electricity unless you are confident about what you are doing. The posts are all independent, if you are splicing two 3 core cables you only need to use three of the posts - earth to earth- live to live- neutral to neutral.

**Q: Does this have a controller for multiple lights?**
A: As others have said and clearly states in advert, its a junction box and not a very good one at that. It is not waterproof nor is it IP66 as stated.

**Q: Is this suitable for an external 400W flood light? Need to disconnect old sensor and direct straight to new flood light.**
A: Hi the Box is fine for this application,You will need a gland as well

### ⭐⭐⭐⭐ Good value
*by G***N on 6 January 2021*

Pros: Holes have been filled with separately injected rubber compound, so seals well. Box is supplied with a 5 way terminal block and a rear clip for mounting - this can be screwed down first then the box is clipped to it. Design is quite chunky and tough. Cons Once a rubber plug has been removed it's hard to then clear the plastic from around the thread to allow the cable gland to be screwed in fully, and there's not much depth of thread. Once the gland is screwed on it seems easy to damage the thread. Having stripped a thread I ended up using PTFE tape to pack it out to stop the gland rotating freely. It's a little difficult to secure the lid with the rotating catches. There wasn't enough room to get the back nut on the gland inside the box. Overall I though it was good value for money and, with the PTFE bodge, worked for my project
