Abstract
A closure for an opening through a partition includes a flange having first and second surfaces and a first extension on a first edge, the flange having a perimeter greater than the opening perimeter. A barrier protrudes from the first surface of the flange and is surrounded by a wall having an outside surface perimeter approximating the opening perimeter. A spring member has a proximal end coupled to a second edge of the barrier and a distal end overlying a portion of the flange first surface including the first extension. The spring distal end has a contact portion confronting the first extension and a knob for manipulating the closure toward the opening.
