French cleat

A French cleat is a way of securing a cabinet, mirror, tools, artwork or other objects to a wall.

The method has been described as simple and strong,[2] but also elegant since it often can be mounted hidden behind a cabinet.

The cleat will not be seen while in use, so it does not matter where it is drilled; this means that it can be screwed into wall studs relatively independent of the lateral position of the cabinet.

Because no fine maneuvering is required, even a relatively heavy cabinet can be hung easily this way.

French cleats are sometimes used for making homemade tool boards,[4] or for adjustable shelving.
