A refrigerator cabinet having an outer metal shell and an inner liner spaced from the shell with foamed-in-place thermal insulation therebetween. The cabinet has an outer metal shell open at the front with two side walls and a top wall each folded to provide a front face with an open fold behind the front face. There is a machinery compartment wall near the bottom of the refrigerator cabinet which is bent upwardly and terminates in a curved front lip having a downwardly facing opening. The inner liner has a peripheral flange which is received in the open fold behind the front face along the side and top walls. At the bottom of the cabinet is a bottom rail assembly which includes a metal cross member with each end secured to the front face at each of the side walls. The metal cross member has a strengthening groove extending between the ends and also has two spaced tabs formed to project downwardly into the groove. There is a snap-on trim member extending the length of the cross member and secured along the top edge and has a front vertical wall engaging the front surface of the cross member terminating at the bottom in a reverse bend hook with the end of the hook engaging the tabs of the cross member. The front vertical wall has an open reverse bend at the top to form a rear wall engaging the rear surface of the cross member. The rear wall has an open reverse bend away from the cross member to receive the bottom peripheral flange of the inner liner and forming an upwardly extending leg having a terminal end received in the downwardly facing opening of the lip of the compartment wall. With this structural arrangement the bottom rail assembly prevents egress of foam past the bottom peripheral flange of the inner liner and past the lip of the machinery compartment wall during the foamed-in-place thermal insulation operation.
