ABSTRACT:
In accordance with the present invention a handhold (10) is provided including a base handhold member (12) including a first fastening flange portion (16) and a longitudinally extending rod portion (14). The length of the longitudinal portion is sufficient to meet most if not all distances between fasteners utilized on railway cars and other transportation vehicles. A second handhold member (30) includes a base portion (32) having an opening 34 and an upwardly extending flange portion (40). The base portion slidingly receives the rod portion and thus enables adjustment of the distance between the flange portions. The rod portion thus may be cut at the installation site to meet desired length. In one embodiment the distance D.sub.2 of the second flange above or below the rod may be varied by utilizing a selected member having this desired distance. Also different second members may have selected distances D.sub.1 from the vehicle body. The second member is held in place by mechanically deforming the cut end of the rod portion to prevent exit of the second member.
