Fastening bar assembly for frameless insulating panels

In a fastening bar assembly for connecting adjacent insulated panels of an insulated enclosure, a bar body adapted for encapsulation in a foam core of an insulating panel, an apertured anchor plate on one end of the bar body, and a pod formed of low heat conducting material on said apertured anchor plate, said pod being of unit construction and having a through passage from end-to-end thereof, said through passage being internally screw-threaded in a region inwardly of and between the opposite ends of said pod, at least one end of the pod having a recess leading into said screw-threads for the guidance of a screw fastener element into the screw-threads, said pod having a flange plate on its opposite end extending beyond the peripheral surface of the pod and having at least one straight edge engaging a flat face of the fastening bar assembly and resisting rotation of the pod on said apertured anchor plate, and the pod having a forwardly tapering locking bead spaced somewhat forwardly of the flange plate in parallelism therewith and adapted for snapping through the aperture of the anchor plate to hold the pod captive on the anchor plate with the bead on one side thereof and the flange plate on the other side thereof.
