this set up makes the rope pushdowns we use/do a bit more user friendly. now you know i like to take the hard road, however, with the rope over the top bar, the friction generated at heavier weights makes the rope increasingly difficult to move, hence why it makes a good anchor wrapped around a tree when you're trying to lower something. this is simply a thick pvc pipe slid around the safety pin of the power rack . still hard to do the exercise but your rope will last longer and you'll get more even increases in your strength curve/ weight ratio.
