In cooperation with Michal Zmek on the equipment of the corridor in the FJFI Building, I solved the issue of notice boards. The plus sign components have 4-point magnets and always allow only two positions: the paper clip position and the retracted position. These components are placed regularly according to the dimensions of the A series (A4, A3, A2, A1), so in case it is necessary to place the A2 poster in portrait, all you need is the crosses over which the poster is to be placed, rotated position so as not to interfere with the larger format. By securing the cross to the board, it cannot be stolen like magnets on standard boards.
