The Over the Cabinet collection is so easy to use. There is nothing to install - just hang these over your cabinet door and they are ready to use. No nails, screws or messy adhesives needed. The Over the Cabinet Basket is made of super strong steel wire with heavy-duty chrome Power Lockating. Just pick it up - you can feel how strong it is. We have also added non-absorbent foam pads on the backs of the over door hangers to protect your cabinets.
