bank robbery film

[faxvandal]

Would anyone know the name of a film about a bank robbery (set in USA I think) where the thieves break into the building by using a zip line from the adjacent building and use an elaborate ladder to cross a brightly lit hallway criss crossed with lasers to get to a vault with a safe in it. To work on the safe they have to roll it out of the vault carefully so as not to activate the sonic alarms. When the job is done the ladder is packed up and a security guard looks through a small hole in the hallway door to find all is well. Year unknown but could be around 1980.
