This simple upgrade can make a big difference in keeping your gear organized and easily accessible. The rings can be adjusted effortlessly during the dive by holding them perpendicular to the webbing and sliding. Once a load is clipped to the ring, the serrations bite into the webbing and hold it firmly in place. Sliding D-rings are ideal for attaching the bottom bolt snaps of sidemounted aluminum 80s or stage bottles to the diver’s waist. During a dive, you can easily move the rings forward to compensate for the tanks as they are breathed down and become more positively buoyant.
