Abus KD10 40g/40 Euro Profile Cylinder Brass EN 1303 Emergency Clutch Class 5

Product Overview

The Abus KD10 40g/40 brass cylinder with knob is a high-security Euro profile cylinder lock designed for use with all mortise locks in commercial and residential environments. Holding an EN 1303:2007 1 5 0 0 0 C 5 2 C certification, it delivers Class 5 key security (10 pins with 100,000 possible combinations), and offers resistance to drilling, breaking, and picking. Durability is ensured with a tested life cycle of at least 50,000 operations, and corrosion class C confirms stable function from -20°C to +80°C.

What sets this model apart is its emergency clutch function, allowing the cylinder to be operated from one side even if a key is left in the opposite side?eliminating lockout risks in hotels, multi-family buildings, and healthcare facilities. Bulk buyers such as facility managers and OEMs seeking high-assurance master key systems benefit from consistent upgrade options and patent-protected, anti-pick technology.
