I'm curious if anyone knows how this part is supposed to be secured. Mine isn't attached to anything and it seems dangerous to just have it bouncing around on the shaft. It appears to be in the correct place/position but I can't figure out how its supposed to be secured. It looks similar to this part called a "protector" but its doesnt appear to be identical and I can't seem to find a photo of this piece on anyone else's rigs when searching.
