Mine has four plastic straps that ride a track on both sides and snap onto the top rack. They also adjust it for height. And the center washer arm comes out somehow... I don't remember exactly how right now, but if it can go together, it can come apart

I have a large wood cutting/chopping block. I have a large plastic and a smaller plastic. I use all 3 for various purposes.
I also have a very large breadboard that I use when baking for rolling out doughs etc.
I have a wood cutting board that I love. I do have 3 plastic cutting boards. I dont not like 5he plastic cutting boards as they dull my knives. Do not use glass cutting boards. Glass cutting boards wreck your knives.
