Gate caps are decorative or functional covers placed on the top of fence posts or gates. They serve to protect the wood or metal from weather damage, such as rain or snow, which can lead to rot or rust. Additionally, gate caps can enhance the overall appearance of a fence or gate, adding a finishing touch to the design. These caps come in various materials, including wood, metal, and plastic, and can be found in different styles and colors. Some gate caps are designed to fit snugly, while others may be more ornamental, featuring intricate designs or shapes.
