Floating Shelf Sign Display

Want to display your signs and not lose shelf space? These slide on the edge of your shelf and allow to display "in between" your shelves.

Ikea measures at 20mm, Amazon measures at 15.4mm. Each Amazon shelf comes with 1- 1mm foam strip. I generally size up 1mm from the shelf thickness, that being said, the 15.4mm fits Amazon (or any shelf) ranging from 12.2mm - 14.4mm. There will be a strip of 1mm adhesive foam included for each shelf to help make a snugger fit if desired. Ikea Billy shows 19mm per manufacturer site.
