Plastic adjustable glides are plastic feet that are typically attached to the bottom of furniture or other objects to protect floors from damage.They are adjustable, meaning they can be screwed in or out to adjust the height and level of the item they are attached to.
They come in a variety of sizes, shapes, and styles, and are commonly used with chairs, tables, cabinets, and other furniture pieces. Some plastic adjustable glides may also have a non-skid or non-slip feature to keep the furniture from moving around on the floor.
