What is the term for a device used for displaying caskets two or three levels high?

The term for a device used for displaying caskets two or three levels high is the casket rack. This piece of equipment is specifically designed to hold multiple caskets in a way that makes them easily visible and accessible for viewing by families and mourners.

Casket racks are often utilized in funeral homes to enhance the presentation of caskets, allowing for a more organized and aesthetically pleasing display. This arrangement can aid in the decision-making process for families as they choose a casket that fits their needs.

The other options refer to different items or equipment used in the funeral industry. A casket stand typically refers to a single platform for displaying one casket; a church truck is a wheeled cart used to transport caskets; and a coffin is an enclosed space for the deceased, not a display device. The distinctions in purpose and design make the casket rack the correct answer for displaying multiple caskets at various heights.
