This looks to be a little on the difficult side. I can't make out exactly what type of commercial door you have. My first thought would be to suggest our 79-124 pivot set which can be used on Kawneer doors. Look it over and let me know if our measurements and mounting holes match up to yours. There is also a chance you may want to go with our 79-126 pivot set used by Amarlite. Ultimately, you will need to make a decision on which of the two would make the better match.

I have also placed a video below I would like for you to take a look at for additional information.
