a raised member extending from the base member, the raised member following the opening in the flange to form a substantially rectangular or square raised wall, the raised member having a plurality of mounting tabs extending from the raised wall toward the opening;
a telescoping member positioned within the raised member and movable within the raised member between a retracted position and an extended position, the telescoping member having a substantially rectangular or square wall and a plurality of mounting tabs extending from the wall toward a center of the opening, wherein one of the plurality of mounting tabs of the telescoping member is aligned with one of the mounting tabs on the raised member to define a mounting tab pair; and
a plurality of drive members, wherein 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 member causes the telescoping member to move between the retracted position and the extended position.
