Looking at the front the left side was flush aginst the freezer with no external fasteners. I had screwed the standard into the collar and had no idea how I was be able to get this detached. I built the collar with a butt-end joint (no need to be fancy since I was coveing it anyway). It just so happens that the screws went in the seam of the joint. Bad construction, but it allowed me to knock the back of the collar off, and get leverage to pull the other peices off without dammaging any of the frame or exterior. Lucky...
