The offered Brick Mould is the outside frame of molding that encloses the window on one side, and the opening of the structure on the other, providing a tight fit that keeps the elements out with a decorative touch. It is the moulding around a window or door, where it meets up with the brick. Sometimes this brick molding can be ornate and decorative, other times it can be plain. Brick Mould is a strip of material used to close the small gap between a brick wall and the frame of a door or window set into the wall.
