Abstract
A capture block assembly prevents unauthorized removal, swapping, interchanging or replacement of shackle members used with conventional wire rope sling assemblies. A first half member is permanently joined with a second half member within a thimble member of a sling loop, after a wire rope sling has been manufactured or assembled, to prevent removal of a shackle from such loop. No welding or other operations permanently affecting strength properties of the thimble or sling member is required.
