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.

Abstract: An underground station is provided with an access cover assembly including a frame extending about an access opening and a cover hingedly attached to said frame. A support member is attached to said frame and extends about the periphery of the access opening. Attaching members are slidably mounted to said support member so that they may be positioned to any desired location about the periphery of the access opening. Fastening means are provided for fixing said attaching members at desired locations about the support member and for fastening station accessories to the attaching member so that the accessories may be mounted in preferred locations in a particular station.
