Vance 16 X 20 inch White Built-in Surface Saver Tempered Glass Cutting Board, 716200, 16 x 20

One of the reviews is saying that the metal frame around this cutting board is teal is that correct ?? It looks gray in the picture ?

How do I remove my old one to install the new one? How do I uninstall the frame?

Is this safe to put an airfryer on ?

do you have a frame that has a solid enclosed trayed bottom ? to help prevent any liquids from entering below the countertop ?
