Yes—the tool targets the metal strike plate or hinge; the surrounding frame material is not a factor. Q 2 | How much can I move the door? Expect about ±1 mm per twist. Apply gradually until the latch aligns smoothly. Q 3 | Could I damage the hinge? Only if forced too aggressively. Gentle, supported twisting won't harm standard hinges—avoid thin decorative metal. Q 4 | How do I protect brass finishes? Place a strip of masking tape over the contact area before inserting the slot to prevent scratches.
