Ikea Billy bookcase topper (Davisville)

This adds one shelf to the top of the famous Billy bookcase. It may also fit other Ikea units. I don't see it on Ikea's site anymore, but this fits the 24" x 11" size, of any height. To be precise it is 11 5/8" wide x 11" deep x 13 5/8" high. So that last number is how much to add to your current height to see if if fits under the ceiling. :-) There are little hidden holes for pins to lock the add-on to the bookcase so it doesn't come crashing down. I don't have the pins, but almost any cut off nails or the like will work fine. I can probably find some for you if needed.

White, as shown. Clean and in very good used condition.
