What is an Air Tray primarily used for in funeral services?

An Air Tray is primarily used as a transfer container that consists of a wooden tray with a cardboard covering specifically designed for the transportation of a casket. This type of container is lightweight and intended to provide a basic level of protection during shipping while ensuring that the deceased can be transported efficiently and hygienically. The design allows for easy handling and compliance with transportation regulations, making it suitable for funeral services that require casket transportation, particularly for long distances or air travel.

The other options do not correctly describe the purpose of an Air Tray. A fully metal casket is not what an Air Tray is, as it refers to a casket intended for more premium funerals rather than a transport solution. A decorative box for storing memorial items does not align with the functional purpose of an Air Tray, which is not for storing, but rather for transporting. Lastly, a protective garment for the deceased does not relate at all to the Air Tray's designed use.
