Product Overview

The Yale Y600 Euro profile cylinder set (40/50+40g/50, brushed nickel) delivers high-security access control for both interior and exterior doors in residential or commercial buildings. The set is certified to class 6.D (atest 160B0C6D) and features a secure coupling mechanism that allows door operation even when a key is inserted on the opposite side. Each pack includes two cylinders (one standard, one with thumbturn), six dimple keys, and a key card for code duplication.
