B-Harko DR STRONG Cylinder Lock Set 30/35+30G/35 Black Unified Key PN-EN 1303

Product Overview

The B-Harko DR STRONG Cylinder Lock Set in black (sizes 30/35 and 30G/35) is suited for commercial and residential door access management, providing enhanced security with two matched cylinders and six dimple keys. This set includes one cylinder with an ergonomic knob and one double-sided cylinder, allowing unified access with a single key for multiple doors. The cylinders are certified to PN-EN 1303:2015-07, ensuring tested durability and security according to European standards.
