An orifice cover is described that is selectively disposed within an orifice having a structural member adapted to extend through the orifice. The orifice includes an inner peripheral extent and both an inner surface and an outer surface. The orifice cover further includes an elastomeric main body having an outer periphery. The outer periphery selectively engages the inner peripheral extent of the orifice and the outer periphery includes a securing mechanism for securing the orifice cover to the orifice.
