When I purchased this, it was called a frame, implying a two-piece item. I asked the size of the insert since it was not in the description at that time, and was then given the size of the insert. (Again, insert implies two pieces.) I did not expect a one-piece item. It is also much heavier than I expected. My intent was to hang it on the wall and now I wonder how I can do that effectively. The size is perfect for my needs though. Because it is the size I need I will work with it, but really did expect a two-piece frame to hang on the wall. .....---THIS IS INDEED A SINGLE PIECE AND WEIGHS ABOUT 5 POUNDS. CUSTOMERS HAVE USED IT AS BOTH A TRAY AND A FRAME. IF USED AS A FRAME YOU MAY WANT TO USE HEAVY DUTY OR MULTIPLE WALL MOUNTING BRACKETS --
