I purchased this for a total gym 1700. This was for the main cable. The original was about 91 inches and this was the closest I could find in size without having too much slack. It fits almost perfectly but there is a bit of tension on cables when the machine is at rest and at highest incline. The rubber stoppers on my machine are a little worn so I just placed a small 1/2 inch thick board to take off the tension. I have used it a few times and everything seems to be holding up well. My original cables lasted 20 years. For this price, if they hold up for half that long then I will be happy. I would recommend this as a good replacement cable.
