color code that often is painted onto the end of the spring can also be used to help determine the correct spring size. Keep in mind that the

color code repeats itself every 100 pounds (example: 100# and 200# will both be

color coded tan)Measure Spring Length: For Example; standard extension spring length for 8' high doors will be 27" without the loop or clips on the ends and will stretch 48" for total length of approximately 75" when door is fully closed.
