These R-hop installation aids are used to help sand the inside of the R-hop to correctly size it to the barrel. These require sandpaper to be used to hold and sand the R-hop down to size. There are the new version 6 tools that have some slight alterations to make them more multifunctional allowing the sanding rod to be used to R-hop alignment. These are detailed in the first video. Directions for it's use are mentioned in the R-hop installation guide and the 2nd and 3rd videos show it's use by it's inventor. The last link is a video of HS5 demonstrating it's use on a Z-kit instalation.
