stuck cannonball door

[Scott Klemm]

The Antique Lock Collector, Vol. 35, No. 3 (July-Sept. 2013) published by the West Coast Lock Collector's Association has an article entitled "Opening Stuck Cannonball Safes." The author, Lynn Collins, used what he calls the "shock method." Hope this helps. - Scott

You stated that you were trying to move the handle CCW. If it is a Mosler cannonball safe you must turn the handle CW to open. That said.... I have an old Mosler Cannonball right now with a stuck door. Has not been opened in 14 years and I suspect interior rust, because the combination sequence works just fine. If you get yours open please let me know how you did it. Thanks.
