A French cleat is a type of wall-hanging system used to secure objects to a wall. It consists of two strips of metal or wood, one with a lip that protrudes outwards and one with a groove that runs along its length. The two strips are mounted perpendicular to each other on the wall, with the lip strip overlapping the top edge of the object to be hung and the groove strip overlapping the bottom edge.
To hang an object using a French cleat, it is first secured to the wall at the top using screws or nails. The bottom edge is then placed into the groove of the second strip and slid up until it locks into place. Theobject will now be securely held in place by both strips.
French cleats are often used in workshops and garages as they provide a strong and secure way to hang tools and other equipment. They can also be used in homes to hang artwork, mirrors, shelves and more.
