Women Installing wall bars that are not stall bars

[gymdog]

Not sure if that makes sense. Basically, I want to install a single rail along a padded wall so it can be used like stall bars for leg lifts, but I don't need or want the other rungs. I've seen this set up in several gyms (Airborne and Monmouth off the top of my head in case that helps anyone). It seems simple enough but we need to install it into a concrete/cinderblock wall.

Does anyone have any advice, plans, or pictures of this?
