ABSTRACT:
A security device adapted to be applied to retain in closed relation container doors for lading against access into the container. The security device has a shelf portion with an upright arm secured thereto and adapted to be disposed in the path of opening movement of one or both of the container doors to prevent opening movement of the doors sufficiently to gain access to the lading in the container. The arm may be a part of an upright angle bar which forms a support for one end portion of the shelf portion while the opposite end of the shelf portion is supported by a rear upright member. The shelf portion is preferably yieldable to accommodate containers supported in different positions with respect to the surface of the transport vehicle. The upright arm may have a laterally extending arm connected therewith whereby the security device will have a retaining device in the path of both doors. Provision is made for discouraging cutting of the upright arm so as to remove it from the path of the door. Such provision may be made by seam welding applied to an angle bar either or both of which would be difficult to cut with a torch or saw.
