high-performance cylinder worthy of the name “progressive.” The combination of a two-way rotary tumbler and a locking bar provides a strong guard against picking or other unauthorized opening. The use of multiple of hardened components ensures high resistance to drilling attacks. With a highly precise and
complex structure, this cylinder offers more than 100 billion possible key configurations. This is truly the pinnacle of what a cylinder should be, providing durability, ease of operation and style. We particularly recommend this cylinder for large-scale residential housing complexes.
