Sargent Mfg. 97-0425 80 Series Lever Hub Spring
The Sargent Lever Return Spring 97-0425 is usually a green color, however we have seen them in blue and red. The red spring has the same dimensions as the green, but the loop on the coil side of the spring was closed. Sargent is using this spring as a replacement for all of those springs. If you have a Sargent Panic Hardware, and the lever is sagging, or just hanging, this is most likely the problem. The spring measures 2-1/8" long by roughly 3/8" diameter.
