Customer Reviews

I purchased this item to replace a broken garage door extension spring. The basic installation was easy enough although the job is a lot easier and safer if it is done by two people. The most difficult part is getting an accurate reading of the door weight and the correct tension. My garage door is 30 years old so the previous springs did not have the safety cable. The cable is a great safety feature and can save serious injury or damage. Installing the cable was a bit tricky because the instructions are written in very tiny print. However, once you understand how it works, the installation is simple enough.
