A cable bolt button comprising a continuous sidewall having a first end, a second end and an end portion attached to the first end of the sidewall, forming an inner cavity. The cable bolt button forms an interference fit between the sidewall of the cable bolt button and a cable bolt when the button is placed over the distal end of the cable bolt. The cable bolt button may also include a plurality of protrusions extending outwardly from the end portion away from the inner cavity and/or at least one recess. The protrusions may be separate features of the end portion or the first end of the sidewall may have a non-linear profile with the periphery of the end portion following the profile of the sidewall to form the protrusions and recesses. The end portion may also comprise a plurality of intersecting surfaces further shaping the protrusions and recesses.

A truss shoe for a roof support system includes a bolt receiving section, an intermediate section, and a housing having a threaded rod engaging section. The threaded rod engaging 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. The passageway has a threaded portion extending from the first end of the passageway toward the second end. A stop member is positioned spaced from the first open end of the passageway. With this arrangement, the end of the threaded rod passes through the space between the first open end of the passageway and the stop member into engagement with the stop member, whereby all of the threads of the threaded portion of the passageway are in engagement with the threads of the threaded bar.

A splice tube includes a body, first and second wedge assemblies, first and second plugs, and a securing member that secures at least one of the first and second plugs to the body. The body defines first and second passageways that extend through the body. Each passageway of the body has a first end and a second end. The first and second wedge assemblies each have a passageway. At least a portion of the first and second wedge assemblies are positioned within the first and second passageways, respectively. The first and second plugs are at least partially positioned within the passageway of the first and second wedge assemblies, respectively.

Splice tube with wedge retaining caps

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.
