This is a drive shaft for Yamaha twin pedals. It's perfect for those who are having trouble with the twin pedal connecting rod being too long, even if they are using a non-Yamaha model. With this joint, you can introduce a twin pedal without changing the position of the hi-hat when using a single pedal. As far as I know, it's the shortest one available? I myself use it with a DW9002XF. There are some scratches and dirt. Please consider it to be in player's condition.
