A spreader bar assembly provides a rigid elongated support of uniform cross-section (for example, a section of pipe). A pair of lifting eye assemblies are connected during the lifting operation at each respective end portion of the bar, each forming a connection with an above supporting bridle line and a depending lift line, each of the lifting eye assemblies comprising in part a socket of uniform cross-section receptive of one end of said bar thereinto and having a corresponding internal cross-section equal to or slightly larger than the external cross-section of the support bar. A stop is provided within the socket for limiting the penetration of the bar into the socket.

A spreader bar assembly comprising: a. A rigid elongated support bar; b. A pair of lifting eye means removably connected during a lifting operation at each respective end portion of said bar for forming a connection with an above supporting bridle line and at least one depending lift line, each of said lifting eye means including an integral female socket for receiving one end of said bar thereinto and having a corresponding internal cross-section equal to or slightly larger than the external cross-section of said support bar; and c. transverse stop means within each of the sockets for abutting the end portion of the elongated support bar thereby limiting the penetration of the bar into the socket, the pair of lifting eye means being freely separable from the bar and held thereto during a lifting operation by forces applied to each of the lifting eye means by load lines attached thereto.
