I have bought two mirrors; 12.5kg and 25kg. They came with plastic dry wall anchors (see pictures) but I am affixing them to the inside of the outer wall to my flat. The wall will be plaster and brick (see attached pic of exposed wall near plug).
What type of anchor do I need? I assume rawl plugs will be insufficient for this purpose. The screws to go into the supplied plastic anchors on which the picture will hang are #8 1-1/4"
Many thanks
