Sydy, my mounts purchased about a year ago came with the plastic guard. It's very thin, but for me it has done the job. I don't want to suggest that Pikey is careless, because it may simply have to do with the desk, but I have no noticeable wear on my desk due to the mounts. Seriously, no complaints other than that there are situations where they need to be just a little longer. If I knew then what I know now, I would have asked Monstertech to add about 3-4 inches to the height of the mount to better support center stick use.
