Abstract
An anchor for securing a manhole cover support to a manhole frame is shown. Dovetail-shaped receptacles are formed at a plurality of locations about the manhole cover support. A plurality of anchor straps having a cooperating dovetail shape are inserted into the receptacles. A lower end of each anchor strap has a threaded bolt extending upward. The anchor straps are simply dropped into the receptacles and the lower bolt is rotated to wedge the dovetail shapes tightly together and, at the same time, secure the manhole cover support against the frame.
