What size tension spring do I need?
For extension springs, you'll need to know the length of the spring, the weight that it's intended to hold and the outside diameter. It is common that most residential garage doors are either seven or eight feet tall. Seven-foot doors usually use a 25-inch spring, and eight-foot doors use a 27-inch spring.
What are tension spring used for?
Tension springs resist the pulling force that is placed upon them and this creates a sling back effect when the force is removed, causing it to return to its original shape. This function makes them ideal for lifting heavy objects and assisting in the lifting or dispersing of certain loads.
