Abstract
A locking apparatus is provided for locking the rear doors of a trailer that has door closing members that include left and right vertical bars on the doors and horizontal clasps that attach respectively to the bars. The apparatus includes a pair of structural blocks that are attached to the doors using bolting or welding for example. A hollow spanning member is transversely positioned to span between the blocks, the spanner member having a central open-ended bore that communicates with preferably both end portions of the bar. Each of the blocks has a receptacle that slidably receives an end portion of the bar. One of the blocks has a vertical channel that extends through the block between its upper and lower surfaces and which communicates with the receptacle. This enables a locking member to be positioned in the channel and form a connection with the bar at the intersection of the receptacle and the channel. The locking member can be keyed or provided with tumblers having a combination that prevents theft if the combination is unknown.
