Bar hangers are essential components used for securely mounting outlet boxes in various construction settings. The correct response identifies the two types of bar hangers as adjustable and solid.

Adjustable bar hangers allow for flexibility in installation, enabling the user to modify the spacing and height according to specific needs in different scenarios or ceiling configurations. This adaptability is particularly beneficial in residential and commercial projects where ceiling heights and distances between joists can vary widely.

On the other hand, solid bar hangers provide a fixed, sturdy mounting solution that ensures stability and strength for the outlet boxes. They are designed for situations where a consistent and secure attachment is necessary, providing a reliable support structure that doesn't require adjustment once installed.

Understanding these two types of hangers helps installers choose the right product for their specific needs based on the job requirements, making it easier to achieve efficient and safe electrical installations.
