In the construction of swing bar hardware, where is the arm attached?

In the construction of swing bar hardware, the arm is attached to the lug. The lug serves as a pivotal point that provides a stable anchor for the arm, ensuring that it can swing effectively. Lugs are specifically designed to withstand the lateral forces applied when the swinging motion occurs, which is critical for maintaining the integrity and functionality of the swing bar mechanism. This attachment point is essential for the overall operation, as it allows for a smooth and efficient movement, making it an integral part of the hardware's structural design. The other options, such as ogee, wings, and body panel, do not function as the primary connection point for the arm within this specific context.
