This is just what I needed to stretch the space in my pantry.  I bought two because my pantry has narrow double doors.  They are just the right size.  Included in the package are two different sizes of hangers, to accommodate narrower or thicker doors.  Also included are suction cups and stickers for the bottom of the doors.  Because of the recessed design of my doors, the suction cups don't work, but the stickers do, and hold the shelves motionless when the doors are opened and closed.  The only complaint I have is that the hangers at the top of the doors are just a smidgen too thick to allow the doors to close completely flat.  However, the inch or two protrusion is a small price to pay for the time saved in searching through the pantry for frequently used items.  I'd buy this item again.
