I’m fixing another curtain rail in the Expanda on the ceiling. I’m wondering how thick the ceiling is….so I don’t have a screw pop out the top. Anyone know?
Not very thick at all, guess 3 to 4mm ply, towel rails are notorious for pulling out.... About the same if you have a tin van or composite panel ... I have screwed/glued a panel to the wall/roof which I then fitted the rail to, spread the load over a wider area....
