ABSTRACT:
An access cover frame for an underground station such as a pumping station is provided with a cleat connection for assembling a plurality of access covers to accommodate various size stations. The access cover frames are formed of members having a base and parallel sides which define an outwardly facing channel. Returned flanges are formed on said sides and cover a portion of the channel. A longitudinally extending cleat connecting member has grooves formed along the length thereof for receiving the returned flanges of juxtaposed frames thereby connecting said frames along the juxtaposed sides.
