Patent ID: 7234221

Claim:
A method of closing an opening through a partition, the opening having an edge defining a perimeter of the opening, the method comprising the steps of: a) supplying a plug comprising: a flange including first and second surfaces and having a first extension on a first edge, the flange having a perimeter greater than the opening perimeter; a barrier protruding from the first surface of the flange, the barrier being surrounded by a wall having an outside surface perimeter approximating the opening perimeter; and a spring member having a proximal end coupled to the barrier on a second edge and having a distal end overlying a portion of the flange first surface including the first extension, the distal end including a contact portion, b) pre-positioning the first extension and distal end of the spring member on opposite sides of the partition so that the barrier is positioned adjacent to the partition opening with the proximal end of the spring member extending through the partition opening, and c) applying a force to the proximal end of the spring member in a direction and in sufficient magnitude to cause the barrier to slide toward alignment with the partition opening, the spring member biasing the barrier toward insertion into the partition opening.
