Help with ridgerunner spreader bars
So I just received my new to me ridgerunner and I can't for the life of me figure out how the spreader bars go together. I think I tried every combo and none allowed the 4 inch extension to fit. Also should the hea end look like the pic below? I seems the end cap never really extends like the foot end. Sorry for the noob question but this is my first experience with a bridge hammock
