Aprilaire #4270 pleat spacers for air cleaner model 2400 / 5000 (6-Pack).  Spacers clip into the plastic inner housing to hold filter media in place and keep pleat spacing even.  Pleat spacers and inner housing can be re-used and only need to be replaced if they are broken or lost. If you have discarded your spacers and plastic inner housing, the entire assembly is available for sale.
