A cap formed with a pan that defines a central dish which receives a portion of the securing members that secure the pan to a manhole opening. A cover closes over the central dish to restrict entry of water and dirt contaminants into the central dish. The cover and the central dish thereby define an enclosure for the securing members which connect the cap to the manhole cover.
