    Abstract: The present invention discloses a tube (14) for rock bolts having either a cable tendon or a rod tendon. The tube is deformed to permit the tube to be coiled and yet also provide good keying between the tube and grout. In addition, a fitting (26, 46) for the rear end of the bolt is disclosed in which a grouting orifice (31) communicates with a cable passageway (34). Furthermore, the use of two or more cable anchors (57) at the far end of the bolt is disclosed where the bolt is intended to be used in poor ground conditions, such as sandstone.
