A low profile tensionable bolt cable system and method of installation. The tensionable bolt cable has a tension cylinder with a constant diameter throughout its length and a threaded exterior. A bearing plate is provided with an opening and a first mating member. The tension cylinder has a proximal and a distal end with the proximal end having an angled interior surface and a longitudinally extending second mating member. The first and second mating members mate when the tension cylinder is inserted into the bearing plate. Angled wedges are inserted into the angled interior surface. A cable is inserted into the tension cylinder and between the wedges to hold the cable with respect to the tension cylinder to prevent the cable from twisting. A nut is threaded onto the tension cylinder, to tension the cable.
