The short answer is yes, a double garage door can be lifted with a single spring. However, there are several factors to consider before opting for this setup.
1. Balance and Safety:
Using a single spring for a double garage door can lead to an imbalance in the door’s weight distribution. This imbalance increases the strain on the remaining spring, potentially resulting in premature wear and failure. Moreover, an imbalanced door places additional stress on other components, such as hinges, rollers, and the garage door opener.
2. Lifespan of the Spring:
Double garage doors are heavier, placing a considerable load on the springs. By using a single spring, it will have to bear the full weight of the door, leading to increased tension and potential wear. Consequently, the lifespan of the spring may be reduced, and it may require more frequent maintenance or replacement.
3. Safety Features:
Many modern garage doors are equipped with safety features that prevent them from closing if an obstruction is detected. When using a single spring on a double garage door, the force exerted may be uneven, hindering the proper functioning of these safety features. This can pose a risk to people or objects in the door’s path if not addressed.
4. Potential Complications:
In some cases, installing a single spring on a double garage door may require modifications to the door’s track and spring system. This alteration can be time-consuming and may require professional expertise to ensure proper installation. Additionally, if a spring were to fail, it would render the door inoperable until it is repaired or replaced.
While it is technically possible to lift a double garage door with a single spring, it is not recommended due to the potential drawbacks and safety concerns associated with this setup. It is always best to follow the manufacturer’s guidelines and consult with a professional garage door technician to determine the most appropriate spring system for your specific door. Prioritizing safety, balance, and functionality will help ensure the longevity and reliable operation of your double garage door.
