Abstract
A truss shoe for a roof support system includes a bolt receiving section, an intermediate section, and a cable engaging section. The cable receiving section has a passageway having a first open end spaced from, and in facing relationship, to the bolt receiving section and an opposite second end, wherein the passageway has a cone-shaped portion having a decreasing diameter as the distance from the first end of the passageway increases to receive a wedge shaped cable retention assembly. The surface of the intermediate section includes a cut out portion that extends from the first opening of the passageway toward the bolt receiving section and terminating at a riser. A locking tube has one end in the passageway in facing relationship to the retention assembly and the other end in engagement with the riser to prevent the retention assembly from moving out of the first opening of the passageway.
