ProSeriesŪ Technical Information

Master Lock introduced the ProSeries® product line in 1992 with Weather Tough® and High Security, iron shrouded, rekeyable padlocks. Intent on providing locksmiths with greater ease and flexibility, Master Lock designed the padlocks to use standard components across the line. Since then, ProSeries® has grown to include solid body padlocks in Brass, Steel and Aluminum to further satisfy corrosion, security and safety requirements. Most recently, Master Lock has added extensive interchangeable core and door hardware cylinder options to create maximum options for padlock integration into facility padlock and door lock systems. Today, ProSeries® is the only product line available for so many different applications, making Master Lock the source for complete commercial security.
