Extension Cable Assembly for 8 Ft tall door – 7 x 7 1/8″

Nothing is more annoying than a garage door that squeaks, groans or moves slowly when you open or close it. There are a number of things that could cause this, but in some cases this is the extension cable assembly. If your cable is worn, rusted, frayed or otherwise damaged, you could have it replaced by a professional; however, this is expensive and time consuming. Another option is purchasing an extension cable assembly from DIY Garage Door Parts Online and replacing it yourself. This assembly is designed for an 8 ft door. This 7 x 7 design is designed for strength. Replace your current cable with this configuration and add years of life to your door. Doing it yourself is easy – follow along with our video below, or check out our tutorial page for more information about the process. Soon, you will have a garage door that operates just as good as new!

Sold as a pair.
