Does anyone have any tips for precise alignment of adjacent metal back boxes in a solid plastered wall? I'm replacing 2 x 1 gang single boxes with a 2 gang box and a single gang box. I'd like to align the boxes so that there is no vertical gap between the installed sockets. They also need to align horizontally as well! Screwfix item code 60079 dual double/single box would be ideal except its for dry lining only. Item code 48234 is metal, but 2 x single only. Anyone tried using conduit fittings to align the 2 boxes with the required space in-between? Did it work? Any other suggestions for correct spacing (apart from use of spirit level and tape measure.....)?
Seen peeps screw a batten to the wall,to make sure boxes are level. This. https://www.tlc-direct.co.uk/Produc...MI4sK437nH4AIVhZ3VCh2FpQV8EAQYASABEgLJh_D_BwE https://www.tlc-direct.co.uk/Main_Index/Boxes_and_Enclosures_Index/Boxes_Flush/index.html
You can get box joining pieces (knockout box spacer) that give the precise spacing, BUT they only work on standard width sockets etc (like white plastic). Some metal plates are larger and these dont work.
TLC do one https://www.tlc-direct.co.uk/Produc...t2UpfN-Zj69JyD8kAVPOt2xe2ZOEsjlxoC5qkQAvD_BwE I'm sure there are many others, just google it.
You could get one of these. https://www.amazon.co.uk/Double-Single-Metal-Pattress-Electrical/dp/B01LY3T3QL Or just leave exactly 1" between the fixing lug centres.
I occasionally use metal conduit fittings to space boxes, or these http://spacerconnect.com/15mm-spacer-connect/
Yes. Again, with both the Spacerconnect and the TLC products, they only work with standard size sockets etc
Thanks to all for your valuable inputs. Sod's Law they will be metal faced socket & fused spur so I'll need to check if the spacing is compatible with the TLC Double + single box.
I often use two 20mm couplers to space back boxes. It does leave a small gap between face plates though.
