Review on Greenlee 608 5 Piston Conduit Types by Julio Solano

Works great. Attached a standard Greenlee cable to the flask, then used a vacuum to pull it through 150 feet of underground line. The butt has convenient attachments on both sides. After the cable was through, all I had to do was attach the cable (cat5e in my case) to the hook on the other side of the piston and pull it through with the cable.
