This Tundra PC Male to PC Female Sync Extension Cord extends the connection between any flash with a male PC (post connection) receptor, and a camera, sync extension, 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.
This is a 12' (3.6 m) straight, male PC to female PC sync cord.
