ABSTRACT:
A cable installation roller or sheave assembly for temporarily supporting cable on an insulator carried by 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. The support arm is angularly adjustably attached to the clamp base and support brackets. The clamping base has a pivotable leg and an adjustable lever actuated clamp latch device which releasably holds the base legs to the insulator. Resilient pads on the leg insides protect the insulator. 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.
