Also known as E-Style and C-style rings, slide these into the groove from the side of the shaft. They provide a wider shoulder than other external retaining rings for a larger retaining surface.

Side-Mount External Retaining Rings

Also known as E-style rings.

Wide-Grip Side-Mount External Retaining Rings

Also known as poodle rings, these thick rings have "ears" that form a large retaining surface to withstand stronger forces than other side-mount retaining rings.
