ABSTRACT:
A trailer lock structure is arranged for use by fifth wheel trailers, wherein a mounting plate is fixedly secured to a trailer bottom wall forward end to receive fifth wheel securement linkage within a cylindrical tube mounted orthogonally to the mounting plate extending therethrough. A latch plate is pivotally mounted to the cylindrical tube directed through a slot of the cylindrical tube and latched to effect an abutment within the cylindrical tube permitting undesirable removal over mounting of the structure to unauthorized individuals and associated vehicles. The use of support leg tubes for selectively receiving support legs therewithin permits the stable support of a forward end of an associated trailer.
