Which part of the casket handle is grasped by the casket bearer?

The correct answer is the bar, which refers to the horizontal portion of the casket handle that is actually gripped by the bearer during the carrying of the casket. The bar is designed for this specific purpose, providing a sturdy area that allows for a secure hold, making it easier to lift and transport the casket.

In the context of funeral service and casket design, understanding the parts of the casket handle is essential for both those involved in the preparation and those participating in the service. The bar's prominence in this function highlights its importance as a functional component in the respectful transport of the casket. Other parts mentioned, such as the arm, bail, and lug, have distinct characteristics and functions, but they do not serve the primary purpose of being the part that is grasped by the bearer.
