Drawer mechanisms are systems that allow drawers to open and close smoothly. They typically consist of slides or rails that support the drawer and enable it to glide in and out of a cabinet or furniture piece. Common types include ball-bearing slides, which provide a quiet and effortless motion, and roller slides, which are simpler and often less expensive. These mechanisms can be found in various furniture items, such as kitchen cabinets, office desks, and dressers. Proper installation and maintenance of drawer mechanisms are essential for ensuring longevity and ease of use, preventing issues like sticking or misalignment over time.
