What is the primary purpose of a cleat in a wooden box construction?

In wooden box construction, a cleat serves a vital structural role by strengthening and supporting the framework of the box. It is typically a small strip of wood that is fastened to the inner walls or corners of the box, enhancing its overall stability and durability. This reinforcement helps to prevent warping or deformation of the box, especially when it is under load or subjected to external forces. By distributing stress more evenly across the box's surfaces, cleats contribute significantly to the longevity and effectiveness of the container when it comes to preserving and protecting the items stored within.
