Best brand of 47mm galvanised back boxes & also mini grid set-ups?

Featured Replies

The boxes are basically the same, buy the cheapest & move on to the next job on the to do list 😉

I found superlec the cheapest for back boxes.

Some have different knockout locations/sizes. Probably doesn't matter in most use cases but worth checking if you have specific needs.

Yeah, told you I was being a .....

What about mini grid stuff? Anyone have opinions on those?

If someone fitted those on display in my house, they’d get 50 lashes, 5 mins to recover, and then 75 more. Yuk.

I hide groups of switches in cupboards etc, when doing kitchens, or even in an adjacent room, as reducing the number of such wall-warts in a domestic dwelling is high up my list.

So dumb question what is a mini grid? Why do you you need them?

@Alan Ambrose posted an image of one above. The back box is a grid formation available in many different variants, but that all take the single switches you can see in the image. Often used for when you need more than four switches (as that's generally the 2G limit). They also come laser engraved with lettering for things like DISHWASHER, TUMBLE DRYER, etc. making it easy to identify individual switches you might not use often.

They are also often a pig to wire. LOTS of cables in the back box, probably fed from multiple circuits, some quite large cables. Each row of switches are on one plate and some designs require you to pull that whole plate of 4 switches forward to get to the terminals.

I hate them and would never fit them to my own house.
