Abus D10NP 55/55 Cylinder Lock PN-EN 1303:2007 Emergency Function Pearl Nickel

Product Overview

The Abus D10NP 55/55 cylinder lock is an anti-burglary insert, suitable for use with all mortise locks in residential and commercial door systems. Certified to PN-EN 1303:2007, it delivers high security standards including resistance to drilling, picking, and snap attacks. Rated for at least 50,000 cycles with corrosion resistance up to class C (-20°C to +80°C), it is engineered for demanding environments that require reliable access control.

Its standout feature is the integrated emergency function (safe coupling), which allows the cylinder to be operated from one side even if a key is inserted from the other. This minimizes risks in access-critical scenarios, such as in hotels or multi-family housing, by ensuring entry is always possible. Recommended for facility managers, bulk procurement for secure door systems, and compliant contracting in certified security installations.
