Commercial Electric Operator Kit

This is a special sprocket that mounts to the drum of the roll up door when you want to add a side mounted garage door opener and your rolling steel door is equipped with a dead axle. That means this is an E/O Kit used for Janus International rolling steel doors that have a shaft that does not turn. They can be used on the left or right side of the door when attaching a jackshaft garage door opener. This kit includes the Janus International sprocket with 72 teeth, fasteners, spacers, struts, and tensioner.
