Stripping Spring Units help eliminate a major production problem that is often caused by flying debris and unequal pressure when a conventional spring breaks. The SSU is designed with a sleeve between the stripper bolt and the spring. The spring fits tightly around the sleeve to help contain shrapnel of the spring if it were to break.

Depending on the die design, when dies are equipped with SSUs; it may only be necessary to remove the stripper plate screws, remove the plate and replace the SSUs.
