MULTI-GANG ADJUSTABLE MUD RING ASSEMBLIES

Abstract:

A rectangular or square 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 rectangular or square opening through the flange. The raised member extends from the base member and follows the rectangular or square opening in the flange to form a rectangular or square raised wall. The raised member has a plurality of mounting tabs extending from the raised wall toward the opening in the raised member. The telescoping member is positioned within the raised member opening and is movable relative to the raised member between a retracted position and an extended position. The telescoping member has a rectangular or square wall, an opening and a plurality of mounting tabs extending from the rectangular or square wall toward the opening in the telescoping member. The rectangular or square wall of the telescoping member includes a plurality of protective members. Each protective member is positioned in proximity to one of a plurality of 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.
