ABSTRACT:
An arrangement to close an unwanted opening in wall is provided wherein the area of the opening when it has been plugged presents a surface which is flush with the face of the wall.
The opening closure system provided permits the use of otherwise surplus unusable modular wall panels to be converted to plain panels that are readily integrated into a swimming pool wall structure. The closure plugs are formed so as to have a dual wall thickness; a central portion having an area co-extensive with the area of the opening to be plugged and a peripheral "frame" portion of a lesser thickness which abuts against the back of the panel portion which frames the opening in the panel. Teeth or mounting screw hole filling protuberance may be integrally formed on the peripheral portion of the closure plug to fill screw or fastener holes present in the wall contiguous to the opening which is to be closed.
