Winco Aluminum Sheet Pan Extender, Quarter,Silver

I learned to use these working in bakeries. Not only does it turn your sheet pan into a cake pan, but you can bake casseroles and lasagna in them too!

This is exactly what I was looking for. It fits perfect for a half sheet pan and does exactly what it's supposed to do.

Be ready to be disappointed unless Amazon and/or the manufacturer does a better job of packing to protect the extenders. They weren’t even shipped in a box, just a paper packing bag. Will be returning.

It is not perfectly level; does not fit the pan perfectly. It is sturdy. It changed the color a little after washing vs same product by other brand that I also use.
