After 8 years of weather, demo jobs, roof wear, sweat, heat, cold, and abuse, I am replacing my old Diamond Back belt system with a new one, not because I have to, but because I just want a new one. This is the best belt system I have ever used. I am passing my old rig onto a helper, and I am sure he will use it for another 8 years. Thanks Diamond Back, for a belt system I can count on.
