  • ADJUSTABLE MANHOLE COVER
    Publication number: 20190145078
    Abstract: A manhole cover assembly has an inner cylinder and an outer cylinder. An upper ratchet mechanism extends axially and circumferentially about an outwardly facing surface of the inner cylinder. A lower ratchet mechanism extends axially and circumferentially about an inwardly facing surface of the outer. The lower ratchet mechanism is configured to mesh with the upper ratchet mechanism at one of a plurality of distinct ratcheting positions. A cover plate is disposed on one of the inner cylinder and the outer cylinder. The cover plate is at a first elevation when the lower ratchet mechanism meshes with the upper ratchet mechanism at a first distinct ratcheting position. The cover plate is at a second elevation when the lower ratchet mechanism meshes with the upper ratchet mechanism at a second distinct ratcheting position. The first elevation is different from the second elevation.
