When installing a door frame, how should the legs be aligned with respect to the framing?

The correct choice emphasizes the importance of ensuring the legs of the door frame are parallel to facilitate proper installation and function. When the legs are parallel, they provide a consistent gap around the door, enabling it to open and close smoothly without binding or sticking against the frame.

Parallel alignment also helps in achieving a visually appealing finish and supports the integrity of the door frame, particularly during the operation of the door. Properly parallel legs ensure that stresses are evenly distributed across the frame, which is crucial for maintaining the structure over time and preventing warping or misalignment.

Overall, aligning the legs parallel to each other ensures that the door frame sits correctly within the wall opening and interacts appropriately with the door hardware, leading to optimal performance.
