This shelf is lightweight, looks nice, and was easy to install. It comes with a little level to help you install it properly. There are plenty of mounting holes to choose from, so it is easy to screw it directly into a stud, or to just use holes that are convenient for you. It comes with a plethora of mounting hardware. I mounted mine a bit high up and chose to mount it upside down so that I wouldn't see the three screws that hold the shelf to the mounting bracket.

Did its job for moderate weight items.

Size: 40 Inch, Color: Black, Number of Items: 1

Easy install, a little expensive for its construction. Nice appearance however, flexes under moderate weight not for heavy items.

Great addition!

Size: 40 Inch, Color: Rustic Brown, Number of Items: 1

Floating shelf was super easy to install and is a great addition above my window in my office. I used it to put some display pieces my wife wouldn’t allow me to put over our mantle. Very sturdy and looks great!
