Abstract
An electric box assembly is proportioned to be inserted into a panel opening and be retained therein. The assembly includes a discontinuous ring member that can be spread apart from an intermediate relaxed position and inserted through the panel opening, and then compressed to telescopically insert the ring member in the panel opening. The ring member has an outwardly extending flange for engagement with the outer surface of the panel, and an inwardly directed first cam means. The assembly also includes an outlet box member adapted to be positioned within the ring member and locked thereto. The outlet box member has an outwardly extending flange for engagement with the inner surface of the panel, and an outwardly directed second cam means which engages the first cam means when the outlet box member is rotated relative to the ring member. The first and second cam means cooperate to move the flanges toward one another and into clamping engagement with the panel thereby accommodating panels of differing thickness. The second cam means may comprise a plurality of sets of lugs to enable the assembly to accommodate panels having a different range of thicknesses. The flange on the ring me…
