The Sesam clip-on system, which is attached to the side walls of cleaning cupboards, organises the whole cupboard space. The hose or broom holders, shelf boards and hooks are height adjustable and can be adapted to the items to be stored. The closed base of the simple shelf boards prevents bottles from falling over and small items from falling through. The Libell hooking-in elements form a unit with the fitting. Thanks to the rounded edges, the storage spaces are easy to clean.
