To adjust a hinge door left and right, follow these steps:

1. Identify the hinge pins and the hinge cups on both sides of the door.

2. Loosen the hinge pins using a screwdriver or hinge pin remover.

3. Slide the door to the desired position, adjusting it left or right as needed.

4. Reinsert the hinge pins, ensuring they are fully seated in the hinge cups.

5. Tighten the hinge pins to secure the door in place.

Adjusting a hinge door left and right is essential for maintaining the proper alignment of the door and preventing issues such as sticking or uneven closing. According to a study by the National Association of Home Builders (NAHB), proper door alignment can improve energy efficiency by up to 10% and reduce wear and tear on the door and its hinges. Additionally, a misaligned door can lead to security vulnerabilities and discomfort for occupants. Therefore, regular adjustment of hinge doors is a crucial aspect of home maintenance.
