Garage Door Opener Rail Bending: Reasons Behind It & Signs to Look Out For

If your garage door arm has an improper angle or the garage door opener rail isn’t correctly installed, you likely have a garage door opener rail bending issue. In an ideal condition, when you close the garage door, the door arm must be away from the garage door at a certain angle.

But when you have an incorrectly installed garage door opener your garage door rail will start to point up and down; creating stress on the garage door opener rail and causing the rail to bend.

Length of the Garage Door Opener Rail

If you don’t want your garage door rails to bend, you’ll have to install the garage door opener accurately. And for this, you’ll have to know the measurements of the garage door rails.

For a single light chain drive opener, the garage door rails will be 116 inches, 128 inches, and 152 inches. And for dual light chain drive openers, these lengths will be the same as the single light chain drive openers.  

Now, here are a few signs that your garage door rail requires replacement.
