This 3-inch rigid D-ring is 316 stainless steel, and the ring is connected to the base plate with two Phillips head screws allowing the mounting orientation to be switched between horizontal and vertical. The D-ring can be worn vertically on the waist strap or horizontally on the shoulder. It provides a large area of attachment, which is helpful to cold water divers who wear heavy mitts.

If you change the orientation of the D-ring on the base plate, some divers add a tiny drop of blue threadlocker to the screws for extra security.
