Abstract
A frame is made from a one-piece paperboard blank which is formed in a collapsed shipment and storage blank configuration. The collapsed frame can be manually expanded for use. The corners of the expanded frame are locked by locking tabs and locking slots which hold the frame in its expanded state. The frame can be used to hold air filters which are used to filter the air entering a hot air furnace.
