One problem is that the holes in the arms of the AP are rectangular with

allow the grommet to be deformed to fit the hole.

Yes, similar to how mine was - but mine had plasticky flex. It's getting
flat-3 rather than 3-core that's the challenge, as I don't want to break
out the earth from sheathed flex.
