1 Gang 20mm Spacer

[securespark]

Is this the sort of thing your looking for but 20mm? (could you use 2 of these?)

Yes. Could use 2, but there appears to be a ridge on one side preventing this.

I think I might invest in a new jigsaw and cut the back out of a PVC box.

My preference is a circular saw bench. Put the base of the box against the fence and adjust the fence position as required and have the blade up just enough to go through the thickness of the wall. Takes 4 cuts (one each side) and then the internal pillars need to be finished off (I do them by hand) and threaded inserts removed. Actually, removing the inserts first might be a good idea depending on where you cut goes.
Putting the back of the box against the fence means that if the box moves away from it, it leaves extra material on the bit you want, rather than taking too much off.

Have to admit though - I've only done this on soft(ish) plastic boxes. I can't see why it wouldn't work with the hard ones with care.

I'm just curious - assuming, as seems to be the case, we are talking about a surface-mounted 'pattress' box, why can't it simply be replaced with one of the required depth?

Kind Regards, John

I have only used PVC spacers where you need to fit an accessory that needs a deeper box than is currently chopped into the wall and for whatever reason you're unable to cut the wall out ie UFH thermostat, dimmer switch on a 16mm box etc so I assumed this was the same scenario

Indeed. I suppose it's the "whatever reason" that I was curious about.

sparkwright, What does YTLP mean?

Perhaps he is being polite: You Try Looking Please?

After all, you obviously did not even make the slightest attempt at using the internet to discover if your statement was accurate before posting it.

And "you obviously did not even make the slightest attempt at using the internet to discover" the answer to your problem.

And I note your advice to always use the internet to check accuracy of any advice, like wikipedia? When what you really mean is always get someone else to do your internet searches.
