I could have used this when I first bought mine! I got a bunch of pieces in a plastic bag with no instructions.
Sure, I thought, how difficult can it be? I’ve put together any number of bridles in the past. Creating a side pull bridle was a piece of cake. Figuring out some of the other configurations was, well, more challenging. All I can say was I was glad to have a photograph from the website and a husband who is an engineer.
