This system is used to maintain the tension of your strap around an object (or a person, during an artistic performance). If you want to stretch your strap with the strength of the tensioner, you're screwed. The strap will jam the system. This is guaranteed on invoice. La Corderie explains the instructions in two steps to avoid this inconvenience: 1. Nature has given you biceps, put them to work. Pull the strap with your hands. 2. Once the strap is tight, activate two or three of the ratchet tensioner to maintain tension. That's it. What, already? It's so fast that it's outrageous.
