What is the purpose of a gasket channel in caskets?

The purpose of a gasket channel in caskets is to hold the gasket that seals the casket. This gasket is typically made from materials such as rubber or a similar substance and serves a critical function in creating an airtight and watertight seal when the casket is closed. This sealing capability is essential for preserving the integrity of the casket's contents, providing protection from external elements, and ensuring that the body is safeguarded for an extended period.

While support for the casket lid, aesthetic appeal, and accommodation of the body are relevant considerations in casket design, they do not specifically pertain to the primary role of the gasket channel, which revolves around sealing. The gasket channel is thus crucial for maintaining the casket's protective features and durability over time.
