Garage Door Springs
My neighbor has two large (two car garage) garage doors that are unusually tall (to my experience). These doors have a rail drive chain electric opener and have an unusual spring arrangement. My doors, by contrast, have the large spring on each side that run in the direction of the door travel. The doors at my neighbor's has a large horizontal spring arrangement, running from the left to right side of the door at the top. This spring does the same function as the more usual type I have, I believe.
On one door the spring is obviously broken, and the door will not open because, I believe, the lack of spring connection causes the the door to become unbalanced and the door jambs and will not rise.
I haven't yet looked for a replacement spring, but as it is unusual to my experience I make this post in case anyone who has experience with this type of spring has any advice to give me before I start a repair.
For one, is this type spring carried by Home Depot and Lowes? The type springs on my doors are carried by HD and Lowes.
