A ring metal (M) installed in a binder (B) stores punched sheets of paper and the like. The ring metal includes binder rings (R) mounted on movable frames (F) to which one end of each ring half is attached. The frames are movable relative to each other to open and close the rings. A ring guard (10) is removably installable over a portion of each ring half, when the binder ring is closed, to securely encompass rings halves (12, 14) forming the ring. The guard encloses the junction (J) where outer ends of the ring halves meet when the rings are closed and prevents a gap from opening between the ring halves if the binder is subjected to a force which would otherwise cause a gap to form between the ring halves and paper stored in the binder to spill out or be damaged. |
