Commercial door pivot

Question

I have a commercial door with a hinge that RESEMBLES Swisco's 79-121. My pivot post has a 1/2" diameter. However, I think Swisco's is only 3/8".
I actually need the piece above the bottom pivot. I just need something that can absorb the 1/2-inch post.

You are correct that the pivot is only 3/8" in diameter. However, most (if not all) of these type of commercial doors pivots are 3/8" diameter. Yours could be an older version of the 79-121 that had a larger diameter pivot pin, but I don't think such a part is made anymore. I would suggest replacing your complete pivot with the 79-121. That way all the parts will fit together. Looking at your photos, you might need to do some extra drilling to match up with some of the holes for the new pivot.
