I'm wanting to mount an 18Kg TV using a universal mount with 6 holes. The positions of the studs are not quite right for where we want the TV to go.
This part of the wall has been built recently to block up an alcove and has 18mm plywood attached to the studs and the plasterboard is attached to the plywood.
What fittings should I use to mount this with? I'm assuming wooden screws would not work since there would only be 18mm of plywood behind.
My first thought was to use a hollow wall anchor like:
But the 36mm depth of plywood+plasterboard means I've not been able to find an anchor long enough.
What are my options?
