Full-size pans are used to store and transport large quantities of fresh and prepared foods. In order to increase the shelf-life of the food and facilitate easy storage, it is recommended that you use a Cambro Full Size Cover w/ Handle (10PPCH) for your full-size pans. The molded-in handles make the lids easy to grip and remove. Many establishments choose to use plastic wrap or aluminum foil. However, this can get expensive over time, and you will not be able to stack multiple pans atop one another.
