BG Electrical 817 1 Gang 10mm Square Spacer

Excellent spacer great quality

Did its job. Make sure your securing screws are long enough to engage in back box.

Does the job of giving you more room for wiring if you have a shallow back box. I used this to provide more space so that I could install a smart switch, which tend to extend deeper behind the switch than a non-smart switch. I only needed 10mm and the options were limited. It does the job but be aware that (a) it has rounded corners and (b) it is slightly off white. Consequently my switch + spacer + surround are all slightly different, but this spacer is the most noticeably off-white of the the three (hence the 4 stars).

I'm fitting some smart light switches to electrical back boxes that are not quite deep enough. These easy to fit spacers provide the extra space I need.

Just the jobEasy to fit

I bought this thinking it was grey !!! - didnt read the small print as it arrived white ! ... no point sending it back so will use as and when ... maybe they should have been designed that they could be multi stacked so one can use 2 or 3 to pack the switch out to enable the cables to fit behind or offer different depths 10/15/20 mm but a good altn that smashing the wall deeper and buying a 35mm insert.

These are great as they are specifically designed for the Nexus range so the profile is perfect.We were doing a quick make over of our landing, (eventually it’ll need a full replaster) the previous owner had put sockets on to the batten of the stud wall so the back box was very shallow. Rather than create more work by channeling out the batten or moving the socket, I bought this spacer hoping that it wouldn’t look too bad.I was really impressed the fit was perfect and it allowed me to put the same faceplates as I have in every other room, I might actually keep it rather than cut the plasterboard and install a new back.

As described. Does the job.
