Hi, I've some 11.5 inch hollow space under my balcony window and wanted to see if I can utilize the space for shoe storage. The length is about 9ft. Would anyone know or have contacts to get brackets and shelves/rods, ideally aluminium? The idea is have the shelves slanted from a wall bracket and height is adjustable. Something like display shelves in the library or book store. Appreciate all pointers. Thanks in advance! lak
