K3 is a modular wall system made by Kriptonite. It consists of vertical load-bearing frames and horizontal aluminum shelves. K3 does not need to be fixed to the floor or ceiling, so it is possible to design solutions consisting of modules of different heights, particularly suitable for rooms with sloping ceilings such as attics. Ideal as a bookcase for the study, thanks to its high load-bearing capacity (e.g. large volumes, folders) or in a low composition in the entrance area, bathroom, or as a TV cabinet. Does not require wall mounting.
