The Master Flow 12 in. x 2-1/4 in. x 6 in. End Register Box is made of galvanized steel. This box creates a right-angle, center-end transition from the system run to an air register. It is ideal for a situation where the opening in the floor runs parallel to the floor joists and header. It can be installed using sheet metal screws.
