Ladder stiles are the vertical components of a ladder that provide support and structure. They run parallel to each other and connect the rungs, which are the horizontal steps that allow a person to climb. Stiles are typically made from materials like wood or metal, ensuring durability and stability. In a standard ladder design, there are usually two stiles, one on each side. The distance between the stiles can vary depending on the type of ladder, such as a step ladder or a extension ladder. Properly constructed stiles are essential for the safety and functionality of the ladder.
