Designed to pull up to 4 new cables over existing bundles. The Jackson Tool Overlash Aerial Cable Puller, manufactured by Condux, uses large high-impact plastic rollers that roll easily and safely over existing bundles of up to 2.75" (70 mm) in diameter. Cables attach to quick-connect links and pulling eyes that swivel during pulling to avoid tangles and possible cable damage. Replacement rollers available.
