The beer faucet collar is the top most piece on the faucet lever threads.
When you spin the tap handle (called a faucet marker) all the way down on the threads it may or may not end up facing the direction you want it to.
After you spin the handle all the way down un screw it just enough to face the direction you want it to. Then, un screw the collar up to the handle and tighten it to hold the handle in place. In this way, you tighten the faucet handle in the position YOU want it in. Of course, if you are using a simple black or chrome handle there is no position, so you can just disregard all of our intricate instructions.
