Clamps are used to attach two arms, base adapters and strobe adapters together.
Newer style clamp allows 15 degrees side to side movement of the balls. The new style clamp (AC-CSB) is needed to put between the two new arms if you want the arms to come together when you are handling the whole system topside. This clamp weighs 1.3 oz more than the regular clamp.
