ABSTRACT:
A refrigerator cabinet feed-through grommet formed of resilient material comprising an outer sleeve section having one end formed with a double flange for sealingly connecting the grommet to the cabinet liner. The grommet has an inner socket section for supporting a rigid tube, enclosing an insulated electrical heater conductor, located in the space between the cabinet outer shell and inner liner. The socket portion includes stop means for seating the tube free edge so as to obviate any contact by the electrical conductor with the end of the tube. The interconnection of the socket section with the outer sleeve section is provided by a frusto-conical shaped lead-in section being sufficiently yieldable to permit the inner socket section to move out of concentrically spaced relation with the outer sleeve section so as to compensate for some misalignment of the tube with respect to the grommet.
