ABSTRACT:
An apparatus for adjusting the height and inclination of roadway and greenway appurtenances includes a rigid annular support ring mountable onto a rigid annular spacer ring sized so as to be mountable onto a manhole and a manhole frame mountable onto the support ring. The manhole frame is substantially frusto-conically shaped. A rigid annular base flange may be mounted around a base end of the manhole frame. A plurality of threaded bores are formed in spaced array around the base flange. Rigid elongate threaded members are threadably mountable into the threaded bores so as to be selectively threadably adjustable in the threaded bores and so as to protrude downwardly from the base flange into engagement, beneath the manhole frame, with a top surface of the support ring when the manhole frame is mounted on the support ring. The threaded members are threadably adjustable in the threaded bores to elevate or to tilt the manhole frame relative to the support ring.
