Well, This is AWESOME as far as the width and the potential for extra storage....buuut it will only work if your rod is hanging higher than a standard closet rod with shelf above.  I found that to hang the dividing bar low enough for even t-shirts to clear the lower bar, it has to be at the bottom of the vertical rods, and then only short skirts can hang from the lower bar without touching the floor.  So super great product if your original closet rod is at least 67 or 68 inches above the floor.  Would be super for little kids closets though!
