We recommend checking the type of wall (solid wall, plasterboard, brick, etc.) to ensure you have the right screws and wall plugs.
For example: On a solid wall, we recommend using 40mm wall plugs and PZ 2 screws with dimensions of minimum 5mm x 60mm. Also take into account the thickness of the mount itself: 25mm for the chosen length of screw.
If in doubt, ask a specialist vendor to ensure you choose the right kind of screw.
