Garage Spring Replacement Torsion Springs
When it comes to springs for your garage doors, there are two types of garage door springs, garage door torsion springs and garage door extension springs. Depending upon the size of your garage doors, there are various models and sizes of garage door torsion springs. Depending on your garage door installation you may have a torsion spring that passes through the middle of the spring or the shaft will contain the spring. If the shaft is a model that passes through the middle of your torsion spring, the spring may be mounted in the middle or on the end.
For your larger commercial garage doors, torsion springs can be as small as 1 3/4 inch and as large as 8 inches in diameter. For residential garage door torsion springs, you’re looking at sizes that range from 1 3/4 inch to 2 1/4 inch inside diameter springs. Of course, if you have custom-made wood garage doors that are heavier than most garage doors you may need a torsion spring that’s even larger.
At each end of your torsion springs, you have what’s referred to as cones. On one end of the torsion spring is the winding cone, on the opposite end of the torsion spring is a stationary cone that’s mounted to a bracket, which is attached to your garage door header to stabilize the torsion spring.
