Abstract: An air brake lock assembly helps to prevent air brake actuation knobs from being actuated. The air brake lock in accordance with the present invention is a theft-prevention device that mounts over the air brake knobs on the dash of a semi-truck cab. It is installed between the dash and the knobs and, when locked, the assembly prevents the knobs from being pushed in. If the air brake knobs cannot be pushed back in, the air brake will remain locked and the truck and trailer will remain immobile. In one embodiment of the present invention, the assembly includes a base and an enclosure for each brake knob. An air brake lock is disposed between the knobs such that the knobs can be selectively locked and unlocked. In one embodiment, the assembly is spring-loaded. In another embodiment, the assembly is not spring-loaded.

Abstract: A tailgate collar locking device encloses the slotted mounting hub of the tailgate, together with the pivot point stub within the mounting hub, within a portion of the locking device. The locking device of the present invention comprises a lock housing, a lock cylinder and a shackle. To prevent the theft of certain models of tailgate that are used in the marketplace, the locking device and assembly of the present invention further comprises a tabbed washer or shim that inhibits twisting of the locking device and does not allow the tailgate to be removed in those tailgate models.

Abstract: A free-wheel lock comprises a cylinder, a sleeve, a lock housing, a cam ring, a cam key, a spring, and a lock pawl, the lock pawl comprising lock pawl extension members. The free-wheel lock that is configured to allow a sleeve of the lock assembly to rotate along with a lock cylinder when the lock cylinder is rotated with an incorrect key or by other intrusive means. The free-wheel lock can be used with an air brake lock assembly whereby the lock pawl extension members are configured to engage the recesses of the locking plates to alternatively lock and unlock the air brake knobs of the air brake lock assembly.
