A helical extension spring is a spring which offers resistance to extension. Design procedures for extension springs can be developed in a similar fashion to the ones outlined for compression springs. A force plate at the top landing measures the ground reaction forces of a human user.
WARNING: Torsion springs, extension springs, and other garage door hardware can cause serious injury or death if not handled and installed properly. The most efficient way to measure the wire size is to measure 10 coils and then measure 20 coils and compare the measurements to the chart below.
If the spring you are measuring has spring fittings installed (cones or drums), you can verify the ID by looking for numbers that are etched into the hardware. For example, a 175 will be visible on spring fittings for 1-3/4" ID torsion springs. Generally, the torsion spring ID is a standard width.
