Improvement in a so-called "floating frame" for manhole covers or
the like. The frame (1) comprises a radially outwardly extending
flange (2) designed to be placed flush with the surface of the
road or the like in which the manhole or the like is disposed,
and a skirt (3) designed to extend axially into the upper part of
the manhole, formed by e.g. a concrete pipe (4) or into an
elongation of such pipe. In order to determine the frame level
with respect to the wall pipe (4) and/or for visual inspection of
the condition or quality of the surface material in which the
frame floats, the frame (1) is provided with at least one
aperture or cut-out (5, 15, 16) in the frame skirt (3), the frame
flange (2) and/or the cover seating (2') in the frame.
