Well made, robust box. Bought it to replace a back box on an existing plug socket in a shed. Took a bit of a gamble on it as was unsure whether it would fit but it fits perfectly.
Not a lot you can say other than it does what it's designed to do.
Quality made, robust, and cheaper than some of the local electrical distributors.
Excellent value for money!
I’m not sure how this should be used but it’s too small for a standard MK grid faceplate. I think it’s possibly miss sold.
Smart looking box for metal
Toolstation stock good quality electrical installation equipment for a wide range of domestic, commercial and industrial installations
It’s a grey metal box that does it job
Good well made item at great price
good quality - a bit over the top as far as gauge is concerned but really robust
Nice and deep good quality.
Does what it is supposed to, fits 6-8 modules
Not a lot you can say about a back box but this one is just fine
