I would like to present a simple IKEA idea using a BROR shelving unit and an ordinary FINTORP kitchen rail with a set of hooks. While I use it as a broom hanger, you can definitely use the set of hooks for anything that needs to be hung.
IKEA does make its own range of hooks for the BROR. But they can only be attached to the BROR post. And sometimes we do need more than one hook on a post. So I imagine the flexible number of hooks the FINTORP rail provides will be very useful to BROR unit owners. And best thing is, it fits right out of the box.
