They can be easily installed by simply sliding or snapping them onto the end of the railing. Some end caps may also include additional features such as built-in lighting or decorative designs to enhance the overall appearance of the railing. Overall, a railing end cap is a practical and aesthetic accessory that adds a finishing touch to any railing system.
