Looking for creative problem solvers out there! Attached are pics of the cable setup where two previous cables have frayed badly. The now-famous training video from Norco illustrates this problem and advises that the bracket needs to be adjusted so the cable passes through the hole in the jamb without rubbing against the edges of the hole. In my case, the cable rubs against the top of the hole.

1. I don’t see that there’s much adjusting that can be done with the bracket, now that all the screws have been installed. There are a couple holes that would allow for initial adjustment, prior to finalizing the bracket’s position with all the other screws. But I think I would only be asking for trouble to try to move it now. Am I wrong? Are there options available to me relative to the bracket?
2. I suppose a person could try to ream out the hole in the jamb, to create space at the top of the hole. I don’t have the tools to do that. I have spoken to the dealership, and will probably ask them to do something about it when I take the trailer in for other service.
3. Alternatively, is there something that could be applied to the top perimeter of the hole to make the opening smoother/cushioned so that the cable doesn’t fray so quickly?
