In a conveyor belt housing access port and elastic closure therefor, for use on a conveyor belt cleaner installation, hinges, catches, gaskets and the like are completely eliminated. The cover is retained in place by inherent tension and includes securing means which may incorporate a magnetic force, or interengaging means between the cover and a continuous rim about the opening. The securement may involve an enlargement of the rim such as a ledge, or a flange and an interengaged groove, or a flange on the cover operatively related to such enlargement. <IMAGE> |
