Abstract
A spreader bar assembly includes a rigid elongated support bar to which a pair of end caps are removably connected for use during a lifting operation. The end caps have sockets that fit over the ends of the bar. Each of the end caps includes three pins mounted on a pair of longitudinally extending plates on the extreme end of each of the end caps. A first pin extends between the plates and a pin is mounted externally on each of the plates. The user can attach slings directly to these pins thus eliminating the need for shackles.
