Sinking boxes too deep

[steptoe]

Yep or just use a spirit level across the fixed lugs, larnacaman mentioned level the top of the boxes but this does not guarantee the alignment why wouldnt it.? like going across the lugs does. Measure an inch between boxes to get a decent spacing. Laser level is good but if you are tight and have no laser/couplers then the spirit level and tape measure method will work just as well.

I think he means an inch between lugs.!

it = 1/2" between boxes to look professional

as for hitting the cavity,

expanding foam is your only answer IME.

then some plasterboard adhesive, or lacking that some bonding with a handful of cement thrown in to help it go off quicker.

Add about 25% cement and it'll go off much quicker

an old bag of plaster will also go off quicker

probably still in the bucket when your mixing it.! :slap

not far from it. quickly mix, throw into wall, push box in and if you take any longer, your going to have to get the hammer and chisel

Half inch is fine whatever gap is specced or whatever floats your boat. Perhaps none of you have had to line up more than two boxes. Believe me the professionals line up across the lugs as not every back box in the van is the same make, perfectly made or perfectly rectangular/square. Its one of the basics of putting boxes in walls and should have been drummed in during your apprenticeship days.

5 years and 20 more down the line and Im still being told how to set boxes.! WTF.!

try measuring the gaps,!

do you understand the phrase BESA ?

makes you wonder how/or/why conduit box lids all fit, or how different switches fit different boxes, maybe they make them all to a standard size,.!?

Hmmmmm.... Try 15 to 20 singles, doubles, and full size cooker type boxes in row within commercial kitchens, medical laboratories etc.... Like Steptoe and others here, we have been in this industry too long, too be taught how to set boxes in walls, ....or any other material or structures...

Whatever line you take.... top, bottom or the lugs ....it's the cutting to that line or lines that makes the difference of the boxes being in line, .....or Not!!!

Like everything else, a little time on the details give you the results you want!!!
