Question: A carpenter is installing a pre-hung interior door and notices that the door slab is rubbing lightly on the hinge jamb. What is the most appropriate initial action to correct this issue?

Answer options:

• Remove the door from its frame and plane the rubbing edge of the door slab.
• Tighten the screws on the hinge leaves on the hinge jamb. ✅ Shim behind the top hinge on the hinge jamb to move the jamb slightly out.
• Shim behind the bottom hinge on the hinge jamb to move the jamb slightly in.

Correct answer: Shim behind the top hinge on the hinge jamb to move the jamb slightly out.

Explanation: If the door is rubbing on the hinge jamb, it indicates that the jamb is bowing in slightly at that point. Shimming behind the top hinge on the hinge jamb would push that portion of the jamb out, creating more clearance and correcting the rub. Planing the door is a last resort, and tightening screws or shimming the bottom hinge would not address the specific rub at the top.
