Book rings, binder rings, snap rings; no matter what you call them, they’re a handy bit of hardware. As the names imply, the rings are most often used for affixing booklets together. This means, among other things, that hand-assembly is likely part of a project’s fulfillment. Since our rings our sold in the industry standard, closed position, one step in the assembly process will be opening them. To open the most difficult small rings, we suggest a common automotive tool know as a seal-ring pliers or a retaining-ring pliers. At Popco, we use a seal-ring pliers with a 90 degree angled tip. We rest the tool on a work bench, lay the snap-ring over the tool tips (making sure that the ring’s hinge pin is at the 6:00 o’clock position). Then, closing the tool’s handle will pop open the ring.
