How to Install Garage Door Strut Kits



For additional help, you can view our How to Adjust Garage Door Top Fixtures video.


Garage door struts stiffen door sections to prevent them from bending or breaking. They also allow the door to open and close smoothly. If the sections are not rigid, the garage door will bind as it opens and closes. Residential single-car doors typically do not need struts unless it is a steel door that is motor-operated. On these, a strut across the top section is recommended to prevent the top of the door from bending if the opener force is not adjusted properly.

This video demonstration uses our kit designed for easier shipping. For more information, you can view our How to Assemble Garage Door Strut Kits video.

You can purchase struts and strut kits on our Garage Door Struts page.
