Patent attributes
A round mud ring assembly includes a base member, a raised member, a telescoping member and a plurality of drive members. The base member has a flange and a circular opening through the flange. The raised member extends from the base member and follows the circular opening in the flange to form a circular raised wall. The raised member has a plurality of mounting tabs extending from the raised wall toward a center of the circular opening. The telescoping member is positioned within the raised member and is movable within the raised member between a retracted position and an extended position. The telescoping member has a circular wall and a plurality of mounting tabs extending from the circular wall toward a center of the circular opening. The circular wall of the telescoping member includes a plurality of protective members. Each protective member is positioned in proximity to one of a mounting tab pairs. In this configuration, one of the plurality of drive members is operatively coupled to the mounting tabs of one of the mounting tab pairs, such that rotation of the drive members causes the telescoping member to move between the retracted position and the extended position.
