panic hardware

This instruction manual for panic bar hardware is taken from this site, where you can find more information or buy it online.

Install mounting plate to inside of gate by using six tek-screws.

I work for a city school system and I will be installing what they call "panic bars" on the outside playground. Do you have any information on how to install exit hardware like this on chain link or welded gate frames?

We have a problem with which we hope you can help. Two years ago we had a chain link fence and gate installed. Now the fire department informs us we need to have panic hardware on the gate. The gate we have is 72" wide and has corner posts that are 2 1/2". I looked on the website and I can't find anything that might work so I was hoping you could help.
