I have 20mm previously drilled holes in double thickness insulated plasterboard.

I think a toggle bolt will be the most appropriate, but I’m struggling to find something that will be appropriate given the thickness of the wall and the insulation.

Any recommendations welcome!

Edit: I’m hanging a 12.5kg mirror, but the large holes are already there.

  • Can you give us an idea of what you're trying to hang and the weight?

These toggler anchors will work for thin to very thick walls.

You do not say what the insulation is, The insulation may be a factor in getting them to toggle into place properly. I sometimes use a wire to push fiberglall insulation aside a little so they sit properly.

I have posted several answers about installing these anchors read a few for info and tip/tricks.



use the nut of a toggle bolt but substitute threaded rod (or a longer machine screw) for the screw part.
