External E-Style retaining ring in carbon steel, phosphate finish. Perhaps the most popular and widely used radial retaining ring is the E-Style, (so named because it is shaped like the letter E.) Three prongs make contact with the bottom of the groove and provide a shoulder for effective retention of assemblies.
