When purchasing a new garage door, it can be tempting for homeowners to try to save money by using the old track. However, it's important to consider that the compatibility of the old track with the new door may not be suitable. Factors such as the thickness of the sections, the weight of the door, the required headroom, the position of the garage door opener, and other considerations play a crucial role. The track and sections of the garage door work together as a system, and for optimal performance and durability, it is recommended to use the track specifically designed for your new door.
