It can keep up with the most demanding production rates and wrap almost anything. Since the load remains stationary, this system is ideal for wrapping very light, very heavy, tall, or unstable loads. It is also great in wash down and dusty applications. Wulftec’s wrap over clamp ensures the tail is secured and additional features ensure lower maintenance and better reliability.
