‘Labyrinthe’ plate

This smart system is made up of two symetrically arranged plates on either side of the artwork that is to be hung.
The complex notch in which the wall screw is held stops the artwork from being hung off by someone who does not know how the system works. This very thin plate (1 mm) can also be used to hang the picture flush against the wall (take care to allow some ventilation space, if necessary).
They can also be used as an anti-theft system e.g. under plinths.
