Abstract: A tubular dunnage bar of rectangular cross-section has an inner wall, an outer wall and two side walls. The inner wall has a slot extending lengthwise of the dunnage bar. A channel extends lengthwise within the dunnage bar. The channel has a bottom wall spaced from and parallel to the inner and outer walls of the dunnage bar and side flanges secured to the side walls of the dunnage bar. The channel and the inner wall of the dunnage bar form a pocket. A dunnage strip is received in the pocket and has a nose projecting outwardly through the slot. The channel and the side walls and outer wall of the dunnage bar form a space. The bottom wall of the channel has a trough-shaped, strengthening portion displaced downwardly into the space. The trough-shaped portion of the bottom wall of the channel is arcuate in cross-section and is located midway between the side flanges of the channel.

Abstract: A support rack for releasably and securely holding and separately supporting a plurality of objects. The rack has a plurality of arms each of which is constructed to support a separate object such as an automobile frame. The arms of the rack are linked together such that when an object is placed on a first arm, a second arm is moved into position to receive the next object to be loaded onto the rack. When the next object is loaded onto the second arm, a third arm is moved into position to receive the next object to be loaded onto the rack, and so on. In addition to moving the succeeding arm into position to receive an object, when an object is loaded onto an arm a lock adjacent to the preceding arm is preferably also moved into a locking position securing the object on the preceding arm.
