When you have a variety of containers, it is nice to have a cover that can be used with any of them. The Cambro 12, 18 and 22 Quart CamSquare® Seal Cover (SFC12SCPP190) works well with a variety of Cambro square containers. The polyethylene plastic is durable, long-lasting, and highly versatile. Because the lid is dishwasher safe, you have the comfort of knowing that no matter what you get on it, it will be sanitized and clean after each use. You can also stack the lids with others like them when you don’t need them.
