There is no banjo chain what they are pointing to is the banjo for the safety chain. The banjo is the cut out that in the frame of the dolly that you put the safety chain through. Google banjo eyes for chains to see what they look like.
FYI love our Acme. Hit a turnaround because of a road closure this year and even as tight as I had to turn no damage to dolly or car. Tracks great and the light weight makes it much easier to hand roll into the back of the RV spot at the campground.
