Take one of the three set screws from the side of the CP rail, thread it up into the frame through one of the two holes in the bottom used to mount the rail (hex side up) then use a hex key through the hole inside the frame (under the battery) to pull it up the rest of the way. Then slide the on/off onto the frame and tighten that set screw down from inside the frame to clamp the on/off in place.
