This cord is about 11 inches relaxed and over 3 feet extended.  The cable is rugged yet very flexible and 3 mm (1⁄8") in diameter.

This cord can be used to connect the Nikon SB-24, 25, 26, 28, 28DX, 80DX, 800 and the Canon 580EX II to a device requiring a standard male PC connector.

One common application is to connect these flash units to an optical slave such as Item #0050 from FlashZebra.com.

Another common application would be to connect these flash units to the 4 channel V1, V2, or V2s style of inexpensive radio slaves sold by Gadget Infinity, and other photographic merchants.
