FAQ
Q 1 | Will this work on wooden jambs?
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.
