The first time I tested out my new Backplate and wing I had the opportunity to thread the camband. Not knowing how a friend and I spent a ridiculous 20 minutes attempting to tighten the strap. While cleaning my gear at home I discovered there had been a simple diagram on the buckle the entire time, which I had overlooked. Feeling very foolish I learned to thread it right this time (we never had gotten it correct earlier) So if you're having trouble... read the directions or in the absence of instructions here are a few photos to help.
