The GFSP is the result of a study conducted by the DoD Lock Program in which the need for a medium priced, exposed-shackle padlock was identified.  The GFSP is an excellent choice for a wide variety of applications.  And, the GFSP provides resistance to forced entry equal to the hardened chain or hasp that should be used with it.  This padlock is recommended in applications where padlocks are exposed to grit, corrosive environments, or freezing conditions.
