This is a seal that fits between the base of the SB-900 and the Nikon D700 camera's body to keep the hot shoe contacts protected when the SB-900 is on the camera. This is a new accessory from Nikon. See Nikon WG-AS3 Water Guard for an imge and description. If I were shhooting in an environment that required this, I would also have additional protection for the camera and lens.
