ABSTRACT:
Disclosed is an apparatus which allows for selective employment of a plurality of collapsible support cores to provide shoring support to the interior walls of cabinets during insulating thereof. The cores can be selectively interchanged to utilize a core which corresponds to the size and shape of the particular cabinet to be insulated. Each of the support cores are insertable into the interior section of a cabinet and expanded therein to position a plurality of shoring panels, including separate corner shoring panels, into supporting engagement with the interior walls of a cabinet during insulating to prevent bulging of the interior walls associated with the insulating. After insulating, the core panels are retracted away from the cabinet interior walls so that the core can be inserted into and removed from the cabinet interior without contacting the interior surfaces during insertion nor removal. Particularly, the non-operative cores remain stationary as the selected operative core is expanded and collapsed.
