So instead of a friction saver does anyone know of a friction creator that I can hang on a crane cable? I rent a crane a lot and time is money, but I'm on my 4rd zigzag in 2 years. I've played with using a nub as a friction point and having the zigzag wide open whilst lowering myself with the tail of my line, but I can't always leave a nub in a safe place to do that with. I have tried xrings.
