This 16.5' sync cord provides the necessary connection between a power pack or monolight that has a 1/4" phono plug socket, and a camera, or triggering device that has a female PC (post connection) terminal.
Straight cords are lighter, and usually more economical than coiled cords; coiled cords stretch when necessary, and are more heavy duty than straight cords.
Premium sync cords have gold-plated ends, for longer lasting sure connections.
Some units this items will function with are by: Photogenic, Speedotron, Profoto, SP Excalibur, and Hensel.
