Static-Control Twist-Lock Adjustable-Length V-Belting

This belting limits static electricity discharge for hazardous applications such as fuel transfer and solar-cell manufacturing. Twist the tabbed links together to form a belt. Because the belting is made of individual links, you can change your belt length without dismantling your drive.
