Paragraph Number

139

Side cuts or windows 866 communicate with the passages. Each passage receives a locking bolt 868 in axial sliding and rotating relationship. Each bolt 868 traverses one of the windows 866 exposing the portion of the bolt 868 within the window for manipulation. A knob 870 may be connected to each bolt 868, such as by pinning, to allow a user to rotate the bolt 868 about the passage axis 862 and to serve as a limit to axial travel of the bolt 868 as the knob abuts the proximal or distal margins 872, 874 of the window 866. Each bolt 868 includes a smooth cylindrical portion 876 sized to fit into a trailing portion of a stepped cylindrical cavity in one of the fastener legs. Each bolt 868 may include a threaded portion 878, distal to the smooth portion 876, sized to screw into a threaded leading portion of a stepped cavity in one of the fastener legs.
