The answer to 'how does fence work' is that a fence is a physical barrier used to enclose, separate, or protect an area. Fences are typically made of wood, metal, or vinyl and are installed to provide security, privacy, and define property boundaries. They can also serve decorative purposes and enhance the overall aesthetic of a landscape.
Fences work by creating a physical obstacle that prevents people, animals, or objects from passing through. They are anchored into the ground, usually with posts that are spaced at regular intervals, and the fence material is then attached to the posts. The design and construction of a fence can vary depending on the intended use, the local climate, and personal preferences.
