What type of spring system comes with my new garage door?
Garage doors purchased through retail chains are generally supplied with standard extension springs on single car garage doors (10′ wide and under) and EZ Set torision springs on two-car doors (garage doors over 10′ wide). Professional dealers will install the spring that is best suited for the site conditions. Consult your local dealer or retailer to determine the type of spring system that comes standard with your door.
