This 2" x 14" x 3/8" plate is designed to be used with our Piano Hinges as a stiffener plate to make our piano hinges stronger for heavy use areas. It is not required for most installations unless you want to "beef up" your hinge system.
See the attached image for its intended use/ installation. When looking at the attached image this is item #2.
