I've noticed on newer Safari snorkelss that the snorkel clamp is black instead of plain steel. When did this change? Does anyone know of a source for black clamps? This is another one of the annoying details that I can take care of while the big bitch is at the spa...speaking of which, does anyone know the diameter of the snorkel at the clamp? I might try to find an alternative source, I don't even want to know what the ARB-brand clamp is like. Thanks in advance!
