Abstract of the Disclosure A cover assembly for a ground opening, such as a manhole or a storm drain, is disclosed. The cover assembly includes a frame having a top, a bottom and a tubular sidewall section which is open to both the top and the bottom of the frame.

A core is slidably insertable into the tubular sidewall section of the frame so that the bottom of the core abuts against the frame abutment portion. The core includes a tubular through opening adapted to receive and support a cover such as a manhole cover or a storm drain cover across its upper end. The frame is constructed of a metallic material while the core is constructed of a non-metallic material, such as plastic, to prevent seizing.
