Abus KD10 55g/40 Euro Cylinder Lock Brass Pre-Snap Function EN 1303 Class C Knob

Product Overview

The Abus KD10 55g/40 is a high-security Euro-profile cylinder lock with emergency function, designed for use with all mortise locks in commercial and residential buildings. Certified to PN-EN 1303:2007 and class C for corrosion and burglary resistance, it withstands a minimum of 50,000 operating cycles and temperatures from -20°C to +80°C, making it suitable for demanding environments and external doors.

The standout feature of this model is the pre-snap function, which provides enhanced protection against cylinder snapping, a common forced entry technique. This reduces security risks for facility managers and procurement teams responsible for high-value or public-access environments. Especially recommended for bulk procurement in projects demanding top-tier break-in resistance and long-term reliability, such as multi-tenant commercial complexes and sensitive institutional facilities.
