What part connects the handle of a casket to the lug?

The correct answer is that the part connecting the handle of a casket to the lug is called the "arm." In the context of casket hardware, the arm serves as the essential link between the handle and the lug, which is the part affixed to the casket itself. This connection is crucial as it not only supports the handle's function but ensures that the casket can be securely carried.

The arm typically provides both structural integrity and aesthetic appeal, allowing for smoother movement and an elegant appearance when the casket is being carried. Understanding the role of the arm is important when discussing the design and functionality of casket hardware.
