Yale Y600 Cylinder Set Euro-Profile 35/50+50g/35 Black Class 6.D Safe Coupling

Product Overview

The Yale Y600 Cylinder Set 35/50+50g/35 Black is a high-security euro-profile double cylinder set, including one knob cylinder and one standard dual-ended cylinder, supplied with six matching keys and manufactured in a unified master key system. Designed for commercial, institutional, and high-end residential door applications, both cylinders are certified to class 6.D (160B0C6D) and finished in an elegant black color to suit modern interiors. Enhanced anti-burglary features make this set suitable for installation in locations requiring a high protection level against forced entry, picking, and key copying attempts.

What distinguishes this SKU is the inclusion of the safe coupling (emergency function), allowing the door to be opened from the outside even if a key is inserted on the inside. This eliminates common access risks in hotels, offices, or multi-user residential environments where occupants may leave a key inside the lock. The unified keying system, with six precision-milled keys and a code card for authorized duplication, is particularly suited for property managers, commercial fit-outs, and projects demanding traceable key distribution.
