Costco Insulated Steel Garage Door Failed

During the installation of the CostCo garage door it seems that a setscrew didn’t get fastened down into the torsion bar properly.  You can see that the set screw key-way is visible.  But there are two set screw holes that can be over looked during the install.   These garage doors do not have a very common assembly that can throw off some installers.  The drum can easily loosen up and this is quite a serious issue.  You will need to have the drum

The cause of the failure. You can see the darkened hole mark on the right side of the torsion bar coupler. The screw has wiggled out and has caused the torsion bar to rotate. With the coupler loose the spring assembly freely pulled on the right side of the door. This connection needs to be fully attached together with no movement.
