摘要： The present invention provides a method for producing a full engagement Pittsburgh male lock using specific cutting assemblies and protocols that reduce the amount of metal that is removed from the male portion of the corner notches in the duct. Forming of the male portion of the lock is done after the connecting flange forming has been completed as opposed to before the connecting flange forming has been completed.
