For An Office Cabinet, Supply Closet Or Other Ordinary Application Upgrading To The No. 7040KA-M1 Series May Be Unnecessary But For Heavier Duty Gates, Trucks, Trailers And Commercial Storage Locations Where The Lock Itself Is More Likely To Face Physical Abuse, The Additional ProSeries Construction Makes Considerably More Sense.
