Using the revolutionary Command™ adhesive, the Command™ Picture Ledge holds strongly on a variety of surfaces, including paint, wood, tile and more. Yet, it also comes off cleanly - no holes or sticky residue - providing a great alternative to damaging screws and nails. Reusing the Command™ Picture Ledge is as easy as applying Command™ refill strips, so you can take down, move and reuse it again and again.
