ABSTRACT:
A hole plug for closing an opening in a panel member comprises a rigid, disk-like main body for positioning in overlying relationship with the opening. Resilient retaining legs are carried by the main body for extending through the opening and engaging the edges thereof for maintaining the main body in the overlying relationship. A mass of heat expandable resilient material is carried by the main body at a location adjacent the retaining legs. The heat expandable resilient material is selected so as to be capable of being expanded through the application of heat to permanently extend from the main body a distance greater than the legs to thereby act as a shield to prevent undesired contact between the legs and associated structure.
