This Avantco 360GSKT12248 door gasket for CFM2LB is a direct replacement for the one that came standard on your Avantco countertop freezer CFM2LB. Gaskets are vital to your equipment, ensuring a tight seal when the door is closed and maximum temperature retention. A torn or damaged gasket allows cold air to escape, making your unit's refrigeration system work harder to perform optimally. Be sure to inspect your gasket regularly and replace it if you see signs of tears or damage!
