A fill door for use on the angled surfaces of furnace shells and chemical containers. The door is pivotally coupled to a door frame integral with the angled surface and includes a rim that mates with a female channel in the door. A U-shaped latch is pivotally connected to the frame and includes a threaded spindle operatively connected to crack. The surface of the door includes a female sleeve having a bore for accommodating the end of the spindle when the latch is over the door and the spindle is tightened into its closed and locked position. The door further includes a cantilevered arm having an angled bore which allows it to swivel around a substantially vertical cylindrical post connected to frame. The arm and door swing in a substantially horizontal plane around the axis of the post. |
