A door closure mechanism for use upon a door of a cabinet includes a housing formed from two co-mating first and second members, a drive cam rotatably mounted within the housing, a cam follower mounted within the housing for reciprocating movement relative to the drive cam, and a coil spring mounted within the housing for resiliently biasing the cam follower in a reciprocal manner against the drive cam. The drive cam is formed with cam surfaces which radially engage the cam follower so as to control the relative reciprocal movement of the cam follower with respect to the drive cam. As a safety feature, ther is provided a set of spring pre-load clips which engage the ends of the coil spring so as to prevent full decompression of the coil spring in the event of a housing failure.
