This is a double cable release with a male end and female and fires the male first. It is used mainly for macro rigs to close the lens aperture before firing the camera. Note that the female camera end is made for the older Nikon system from the F and F2 and will also work on the FE and FM but not the later cameras with the larger shutter release button.
The unit is in clean condition with light wear and works perfectly.
