A bulleting board fell in our office and is lay flat against the door, next to a cabinet as well so that it can not be moved horizontally. How can this sentry post be moved without damaging the door or barrier?

Answers:    Unless you can get in through a windowpane, I'm thinking that you'll have to break the bulletin board by forcing the door open -- next to a LOT of force. I doubt that the door will get damaged much, if at adjectives. The bullein board would lose that fight, I'm thinking.

Please be sure to stop back and consent to us know how you got the door open!

If the door swings out-just remove the hinge pins-beyond that try a flat rule below the bottom margin.
