How to measure Garage Door springs www.garagedoornation.com
Measuring your springs • Wire size • Inside diameter • Spring length • Spring orientation (left or right hand wound)
1. Wire size The only way to measure this accurately is to measure 10, 20, 30, and 40 coils and find a match on this chart. It is okay to round if you are very close. Wire size is the most important measurement. This determines the strength of the spring. It is not recommended to manipulate this to try and get a longer life or stronger spring. http://www.garagedoornation.com/pages/how-to-measure-springs
Inside diameter It is very likely that, like 90% of Americans, you have a 2.00" inside diameter. Please double check by measuring just the inside (interior) diameter of the spring. You can measure this while it's still attached.
Spring length • Spring length is the most flexible measurement, but you should do your best to be within 1-2 inches. • The spring length may change slightly after years of use, weather, etc.
Spring orientation A general rule is that if the spring is marked with RED paint, then it is RIGHT wound. Furthermore, if the spring is on the left side when looking from within the garage, it is RIGHT wound. If you have a 2-spring system, you should replace both springs and you can skip this step.
