During the coronavirus outbreak we are not providing an assembly service. In the video above we tried to provide you a detailed instructions on how to build the DT7 Electric desk for the LifeSpan TR1200-DT7 and TR5000-DT7 Treadmill Desks. The video is over 30 minutes long. If you find it too slow, try to play it in 2x speed on you tube. Make sure you build it in the same order we are showing you other wise it will not work.
