At church we have a couple panic bars that stop working, now and again. What I need is a small wrench that's about the shape of letter F. Need to bend a piece of metal a couple degrees, but it's near the lock case. Vise grips or crescent wrench hits the lock case. Need a strange tool.
Off the edge of my memory, didn't they make right angle offset wrench for ignition systems years ago?
I may take a small box wrench, and use a grinder or saw to cut a notch in the end, at the correct angle. Hmm. Might work....
