Modular, Skin, and Multimedia components can Rotate or Lock on the Steroid Speed Belt. This is a tremendous advantage having this type of functionality. Most photographers "Rotate" the bags on the belt, preferring not to lock them into position.
To "Rotate", put the plastic tongue behind the belt, then firmly attach the bag. This allows the bag to be pushed along the belt to the desired position. To "Lock", put the plastic tongue in the horizontal webbing slot.
