A tensioning and handling device for barbed wires, chains, and other similar wires. The device includes a wire-retaining rod, a post-engaging bracket, and a rod-support plate. The post-engaging bracket braces against a running post. The rod-support plate includes a first plate, a second plate, and a rod-receiving slot. The first plate is terminally connected to the post-engaging bracket. The second plate is connected to the first plate, opposite to the post-engaging bracket. The rod-receiving slot normally traverses through the second plate and receives the wire-retaining rod. The wire-retaining rod includes a threaded rod body, a wire-engagement head, and a torque-receiving head. The threaded rod body is threadably engaged within the rod-receiving tool, creating a linear actuator when rotated by an external torque tool. The wire-engagement head receives and holds a wire to be tensioned. The torque-receiving head interlocks with a torque tool to rotate the threaded rod body.
