These are the perfect answer to using a dedicated flash unit off of the camera and yet retain all of the dedicated features of the flash.
These heavy duty TTL cords are designed to fit Nikon Cameras that use dedicated flash units. They feature a molded shoe on one end that slides onto the camera hot show and locks to prevent accidental dislodging of the shoe. A second shoe mounts onto a flash bracket or light stand via either a standard foot with lock or a 1/4-20 thread. The top of the shoe accepts the flash unit. A heavy duty 3 foot coiled cord connects the shoes. Does not have an accessory shoe, and you need to remove the shoe from the bracket and screw it into the 1/4x20 socket.
