ABSTRACT:
A free-wheeling latching mechanism for securing a removable closure frame to a second closure frame includes a latching plate rotatable on a shaft fixed to, and spaced from, the second frame by a flange integrally formed on the shaft. A cap nut is used to retain the latching plate on the shaft during rotation, while providing spacing from the flange, and a sill attached to the second frame is used to support the removable frame during rotation of the latching plate.
