The system that guides the vertical movement of a sectional or rolling closure consists of curved pathways mounted to the garage structure. These pathways provide the structural support necessary for the door to ascend and descend smoothly. Proper alignment and secure mounting of these components are crucial for the door’s reliable operation.
The functionality of this mechanism is paramount to the accessibility and security of the garage. Its design allows for maximized overhead space within the structure. Historically, advancements in materials and engineering have improved durability and reduced maintenance requirements, contributing to the long-term cost-effectiveness of this type of door system.
