This preconfigured unit from String goes narrow and high to provide more than ample storage without taking up too much space in a hallway. Supplied with perforated metal shelves, other String accessories like hooks and rods can be added for a customized solution. And it's also easily expandable with any other String components as needs grow and change—an key innovation of the modular system first unveiled by Nisse Strinning and Kajsa Strinning back in 1949
