Rated 5 out of 5 by from Good Solid Junction Box A good solid junction box. Screw terminals that give confidence to really "tighten down" and not worry about the brass connectors or the plastic mounting columns giving way. Well worth a few coppers more for the HD box.

Rated 4 out of 5 by from Not perfect but not bad These JB's are sturdy enough once fitted providing you don't over tighten them as the threads will strip which is pretty much the same for most JB's. My only real complaint is that the screw heads could be a little more precise however at this price they are still a bargain and I will buy them again.

Rated 5 out of 5 by from Solid and well-priced. This is one of the best junction boxes I've used, both in terms of quality and value for money. I've used other brands where you eventually hear a crack when you tighten the screws - not the case with this one. Highly recommended.

Rated 5 out of 5 by from Heavy Duty Terminal Box You can buy these everywhere, some are good and some are awful. The product I ordered from Screwfix was very good quality and I was able to to tighten up the screws without stripping the threads or splitting the case. Can't ask for more
