ABSTRACT:
A seal lock for use on the access doors of freight cars, trailer trucks and cargo containers or other applications requiring a one time use disposable locking device. In the preferred embodiment a C shaped locking body (10) having locking mechanisms within its upper leg member (14) and lower leg member (16) and a locking pin (30) with its first end temporarily held in place by the locking mechanism within the upper leg member (14). The seal lock is positioned over the hasp and the locking pin is pushed with sufficient force to overcoming its temporarily held position and is pushed through the aperture of the hasp until the first end of the locking pin (30) permanently engages the locking mechanism within the lower leg member (16) while simultaneously the opposite end of the locking pin (30) permanently engages the locking mechanism within the upper leg member thereby securing the seal lock in place by means of a double engagement permanently secured locking means. Thus, the present invention provides a unique one-piece seal lock which protects the double engagement locking mechanisms from the direct pressure of a forced entry in a design which can be used on any heap regardless of the hole diameter within the hasp.
