ABSTRACT:
A cable installation roller or sheave assembly for temporarily supporting cable on a cross member of a pole during installation of the cable onto an insulator. The roller assembly has supporting brackets which include upstanding inwardly bent fingers spaced from one another for containing the cable. A roller which is bearing mounted for easy rotation is held between the brackets. A clamping base mountable to the cross member of a pole surrounds the insulator and in turn carries the bracket by way of a support arm made of insulated material. The support arm is attached to the clamp base and support brackets. The clamping base has knife-edged like forward fingers and a conical leading end of a screw clamp serve to bite into the cross member for secure holding during cable stringing. When the assembly clamp is released the cable can be lowered downwardly onto the insulator and then the assembly when rotated 90.degree. releases itself from the cable. In one form, the support arm is mounted vertically for straight cable stringing runs while in another alternative the arm is angularly mounted for curved road or turned runs of cable.
