It is the body‑side half of a butt hinge; the door leaf attaches to it with a hinge pin. Hinge butts wear, corrode, or get bent from loading dock impacts, causing door sag or closing problems. Replacing a damaged butt restores proper door alignment and seal. The part is steel, typically zinc‑plated, and measures 6 inches in length.
