This FoxFury Rugo 1/4″-20 And Cold Shoe Mount Kit includes two of the four mounts that come with your Rugo light unit. These mounts match those original mounts and are useful as replacements or spares. The 1/4″-20 mount attaches to the top of your Rugo light (not included), while the cold shoe mount attaches to the bottom. The included thumbscrews are used to attach both mounts. The mounting system requires that both mounts are attached at the same time.
