Rated 5 out of 5 by from 40mm pattress Needed these deeper boxes to fit pushbutton timer light switches on a common part staircase, ideal and also a solid box not flimsy as some are very brittle this one is perfect

Rated 3 out of 5 by from Be careful of this one MK used to be the very best quality. They have a good name and are the "go to" brand. I used them for many years in my own home but this recent purchase has revealed a worrying drop in standards. I had to replace a cheap OEM switch that had failed in my house, the first work I've done for myself for a number of years. First off, the box was cracked due to a bad injection, next the receiving inserts for the front screws were mild steel not brass and were very badly finished - they didn't sit flush to the moulding, so the switch plate had a sub-millimeter gap, enough to rock slightly on the box. Then the screw mounting holes were far too close to the central channel to be safely usable. For a 40mm box, you'd think they'd allow for wider channels carrying heavier cables, but the standard outer set of mounting holes was missing completely, leaving only one slip hole in the outer position. This means that there's absolutely no room for drilling a secure, rawlplugged mounting hole, making it very awkward to use for retrofitting over existing cabling - you have to go much deeper than usual in order to get to a firm foundation below the depth of the channel. This leaves the screw's thread uncomfortably close to the cables - over time vibration from the switch operation could slice into the cable insulation if it ended up pushing against the screw. I ended up using the Schneider as the mounting holes were in the same place as the box I was removing.

Rated 2 out of 5 by from Not worth the premium Bought MK as I needed a specific depth of box and this was all I could get it in. The first one shattered as I was removing the knockouts, the second was already cracked when I picked it up, third one was ok, after the most delicate removal of the knockouts I've ever done. The plastic is far too brittle for the purpose, and as someone else commented it doesn't have an earth terminal. Not impressed.

Rated 5 out of 5 by from MK superior quality Bought the MK surface pattress box to replace a cheap quality one that had fractured also replaced the switched socket with MK brand which fits neat and flush with the box. Always buy Mk for the quality construction.
