Abstract

The manhole cover consists of a frame (1) with a rim (11), an inner stop (12) and a hinge bar (4), and a panel (2) with an eyelet (3) to engage with the hinge bar. The inside of the panel has a key (5) with one end (51) which goes under a catch plate (120) on the stop (12) to prevent the cover being lifted if the hinge bar is cut through by unauthorised persons.
