An improved roof support system is described for a mine or the like of the type which includes a pair of plates secured to a roof of the mine at opposite sides thereof adjacent opposing ribs of the mine and a horizontal, transverse reinforcing member extending between the pair of the plates. The improvement described here consists of: the reinforcing member including a first rod means having a first end secured to a first of the pair of the plates and a second end extending toward a second of the pair of the plates; the second plate having a vertical portion thereof with a transversely extending opening therethrough; the reinforced member including a second rod means having a first end with an integral enlarged heat portion with torque applying surfaces thereon, the first end being located in abutting relation with the vertical portion of the second plate with the second rod means extending through the opening with a second end thereof extending toward the first plate; and the second ends of the first and the second rod means including mating threaded means thereon for coupling the first and the second rod means together to form the reinforcing member which is capable of producing tension between the first and the second plates so that the tension may be varied by rotation of the enlarged head of the second rod means relative to the first rod means.
