This SmallRig NATO Rail lets you upgrade your Ronin-S/SC gimbal for compatibility with DJI RS 2 and SmallRig RS 2/RSC 2 NATO accessories. It attaches directly to either side of the gimbal with two M4 screws to support handgrips, monitor mounts, and various other brackets and add-ons. With an optional second piece attached to the other side, you can mount dual handgrips on your gimbal. Besides the NATO mount, the compact rail also provides a 1/4"-20 thread to support 1/4"-20 accessories, such as an articulating arm for a monitor.
