ABSTRACT:
A vandal-proof cross bar assembly for securing the door of a refrigerated storage vault or similar chamber includes first and second mounting members secured on opposing sides of the door, and a cross bar each end of which is secured to a mounting member by a respective shackle lock. The locks attach to pivot posts extending from the mounting members. The posts pivot freely about a first axis, and the shackles each define a loose hinge about a second orthogonal axis, so that with one lock detached, the cross bar hangs freely and moves in a multi-axis articulated motion which prevents vandalism by prying and forcing the bar. In a preferred embodiment the mounting members are placed on adjacent exterior walls of the chamber and an L-shaped cross bar having a main bar and a shorter leg portion fits about a corner to engage the members and secure the door. The main bar pivots about the longitudinal axis of the shorter leg portion.
