ABSTRACT:
An accessory suspension device for an existing binder is formed by an angle strip having slides which can be pulled out so as to project from opposite ends of the spine to suspend the binder. The device fits on the rings of the ring mechanism of the binder and acts to support the ring portions which actually carry the sheets of paper contained in the binder when the binder is suspended by the device.
