I called Jim today. He said the swing gate was supposed to be lifted to rest on the nylon pad. This allows the weight to rest on the pad and not the hinge bolt. He told me he didn't have time due to all other things going on but you could taper the bottom plate so the gate will slide easier into place. Just take it to a belt sander or other kind of sander. The entire nylon pad is black throughout so there isn't a color issue there.

I also complimented him on a job well done.
