Yes, as a standing leg curl; you face the machine and curl out and up using the top roller as your brace and the lower one as the lift point. The top roller height is adjustable for the brace point. Works well.
It does not work lying down (as you can do with a bench) as there is no third roller set available that is horizontal when the machine is "at rest."
The same station has a cable attachment for a bar; I stuck a short length of chain on the bar with a double-ender snaphook and set up that way it works very well for standing bicep curls, which are a good complement to the pull-down exercises.
