Abstract: A cable rack mounted cable puller and installation system for removably attaching to a cable rack and efficiently removing/installing cable upon the cable rack. The cable rack mounted cable puller and installation system includes a first support frame attachable to a first rail upon a cable rack, and a second support frame attachable to a second rail upon the cable rack. A shaft is rotatably supported between the upper portions of the support frames to receive a length of cable. A plurality of securing brackets are pivotally attached to a base of the support frames to selectively surround the rails. A plurality of securing fasteners within the securing brackets allow for tightening of the support frames to the rails. A coupler is attached to an end of the shaft for connecting a powered tool thereto to drive the shaft for pulling or dispensing cable. The support frames are preferably comprised of an extendable structure for accommodating cables positioned at various heights.
