Not sure "Original" as advertised. My original is grey. Has 3 attachment points. Black removed the front attachment point. The other 2 are behind. It feels a little flimsy without the front attachment point, but it works for now. Only time will tell if it lasts that long due to the added burden of the remaining 2. Mine lasted almost 5 years and the only reason I changed them was because the rubber wheels have worn out and they get stuck easily.
