How do you keep things from sliding off hutch shelves?

Open hutch shelves should have a raised lip (shelf stop) of at least 0.5"–1" at the front edge, and for earthquake-prone areas add non-slip shelf liners or choose enclosed door configurations. Heavy reference books and equipment always belong on the lower shelves. FindOfficeFurniture.com's commercial hutch shelves all include front lips — call 888-719-4960 if you need specifications on a particular model.
