A turbine seal closure mechanism for sealing an opening in a turbine component or between one or more turbine components. The turbine seal may include a main body having a longitudinal axis positioned transverse to the axial direction of the turbine and having at least one arm for sealing the main body to a surface of a turbine component and configured to fit within a recess in a turbine component. The turbine seal may also have one or more arms coupled to a side of the main body opposite to the first side having arms attached thereto for sealing the turbine seal to another turbine surface.
