Abstract: Arrangements for clamping a large workpiece such as an I-beam to a precision assembly table (or fitup table) or other workpiece support. The clamping arrangement includes a base; a first track supported by the base; a first slider for sliding along the track; a second slider for sliding along the first track, wherein the first slider and the second slider are moveable relative to one another along the first track; a first spacer supported by the first slider; and a second spacer supported by the second slider; wherein the first spacer and the second spacer are adapted to grip the workpiece therebetween.

Abstract: An aluminum rear case assembly (12) for a trailer body (10) includes a rectangular frame assembly (16). The frame assembly (16) includes an extruded aluminum top rail (22), an extruded aluminum bottom rail (24), and a pair of extruded aluminum side rails (26) connecting the top and bottom rails (22, 24). The top, bottom, and side rails (22, 24, 26) are joined to define the rectangular shape. The frame assembly (16) has an exposed side (18) facing outward from the trailer body (10) and an internal side (20) facing inward toward the cargo area defined by the trailer body (10) and attached to the rear end of the trailer body (10).
