Torsion Springs

Measure the length of the unwound spring.
Do not measure the end caps of the springs. If your garage door has
left and right wound springs, measure both, as they may differ.

Next, Measure the Inside Diameter (ID) of the spring. 

Next, Determine the Wire Size.
Measure the length of 10 coils of the spring.
Example: 10 coils measures 2 1/4" = .225 wire size. (See chart below for examples)

If you currently have 2 springs on your garage door, you should replace both springs at the same time.

About City:

Garland, Texas

Garland TX is a city in the U.S. state of Texas. It is a large city northeast of Dallas and is a major part of the Dallas–Fort Worth metroplex. It is located almost entirely within Dallas County, except for small portions in Collin County.[3] As of the 2010 census, the city had a population of 226,876, making it the twelfth-most populous city in Texas and the 87th most populous city in the United States.

In 2008, CNN and Money magazine released their list of the "Top 100 Places to Live", and Garland was ranked number 67. The city's comfortable, hometown feel in the midst of a thriving metropolitan area was just one of the outstanding characteristics mentioned in the report

Settlers began arriving in the Peters colony area around 1850, but a community wasn't created until 1874. Two communities sprung up in the area: Embree, named for the physician K. H. Embree, and Duck Creek, named for the local creek of the same name. A rivalry between the two towns ensued as the area began to grow around the Santa Fe Railroad depot. Eventually, to settle a dispute regarding which town should have the local post office, Dallas County Judge Thomas A. Nash asked visiting Congressman Joe Abbott to move the post office between the two towns. The move was completed in 1887. The new location was named Garland after U.S. Attorney General Augustus Hill Garland. Soon after, the towns of Embree and Duck Creek were combined, and the three areas combined to form the city of Garland, which was incorporated in 1891. By 1904 the town had a population of 819 people.
Dedicated to the city by Rosalynn Carter, the Historic Downtown Garland Square has plans for renovations.

In 1920, local businessmen financed a new electrical generator plant (sold by Fairbanks-Morse) for the town. Out of this was formed Garland Power & Light, the municipal electric provider that still powers the city today.

On May 9, 1927, a devastating tornado destroyed much of the town and killed 17 people, including the former mayor, S. E. Nicholson.

Businesses began to move back into the area in the late 1930s. The Craddock food company and later the Byer-Rolnick hat factory (now owned by Resistol) moved into the area. In 1937, KRLD, a major Dallas radio station, built its radio antenna tower in Garland, and it is operational to this day. During World War II, several aircraft plants were operated in the area, and the Kraft Foods company purchased a vacant one after the war for its own use. By 1950, the population of Garland exceeded 10,000 people.

From 1950 to 1954, the Dallas/Garland area suffered from a serious and extended drought. To supplement the water provided by wells, the Garland began using the water from the nearby Lake Lavon.

Following World War II, the suburban population boom that the whole country experienced also reached Garland. By 1960, the population nearly quadrupled from the 1950 figure to about 38,500. By 1970, the population had doubled to about 81,500. By 1980, the population reached 138,850
