Swivel casters are wheels that can rotate 360 degrees, allowing for easy maneuverability of objects like carts, furniture, and equipment. They are commonly used in various settings, including homes, warehouses, and hospitals, to facilitate movement in tight spaces. These casters typically consist of a wheel mounted on a pivoting fork, enabling the wheel to turn freely. Swivel casters can be fixed or have brakes, providing stability when needed. They come in various sizes and materials, making them suitable for different surfaces and weight capacities, enhancing their versatility in everyday use.
