It is possible to buy extra shelves for Montana's shelving modules in 12 mm MDF. In this way, you can create a unique shelving module, which can be easily changed again as your interior design style also changes. The Montana shelves are available in many different sizes in all Montana colours and it is easy to change the horisontal position of the shelves. This 6X shelf measures 33 cm (inside measurements) in its width and is generation 2. That means that the shelf can be placed in an open shelving module, but not behind doors. If you want to buy the shelf in another generation, please contact one of Montana's many retailers.
