Abstract

In a manhole/access cover and frame assembly wherein two or more rectangular covers 11 are supported in a frame 10 having internally-flanged side members on which the covers rest, each cover 11 is formed with a pair of downward corner projections 28 which locate in respective recesses 29 in the upper surface of the associated frame flange. The base of each recess 29 is sloped whereby when the cover is slid horizontally, for removal, it is lifted slightly as the projections 28 ride up the recesses 29, so breaking any seal. <IMAGE>
