Abstract: Lock-protecting hasp for trailer full swing rear doors having locking bars which secures to the bars of the rear doors and includes two mating members and a shackle lock whether the lock be key or combination. A protecting block against the lock on the female mating member protects the shackle of the lock from being cut or pried off the body of the lock, or between the shackle, the body and the lock-protecting hasp. Longitudinal opposing slots and a ribbed locking bar on the male mating member provide for adjustability between the two members for accepting door bars spaced any distance dependent upon the type of trailer. The lock-protecting hasp particularly lends itself to use on semi-trailers having full swing rear doors and the lock-protecting hasp accepts a lock of predetermined size.

The lock-protecting hasp includes two outside mount hasps, a spacer secured to each of the outside mount hasps, and a protector block engaged to each of the outside mount hasps. The lock-protecting hasp particularly lends itself to use on semi-trailers. The lock-protecting hasp accepts any lock of suitable size.
