The SC-28 provides full TTL control for Nikon Speedlights when used off camera with Nikon D-SLRs that utilize a TTL hot shoe. 

The SC-28 is approx. 9-ft in length and coiled.

One end slips into the D-SLR's hot shoe and the Speedlight attaches to the  other end, when the Speedlight is used off-camera, on a bracket.
