ABSTRACT:
A binder ring has folio stops affixed to the end of at least one binder ring section. When the binder ring is in the open position the folio stop impedes a folio sheet from inadvertently sliding off the ring section. The folio stop slips on when the binder ring is opened and slips off when the binder ring is closed to be unobtrusive.
