B-Harko DR STRONG Cylinder Set 40/30+40G/30 Satin Nickel 6 Symmetric Keys EN 1303

Product Overview

The B-Harko DR STRONG Cylinder Set 40/30 + 40G/30 in satin nickel finish is intended for use in residential and light commercial access control, providing a master-key solution for two locks operated by one key. Recommended for installation in aluminum, PVC, or wooden doors, these cylinders are certified to PN-EN 1303:2015-07 and rated for 100,000 operating cycles, with corrosion resistance from -20°C to +80°C. Each set includes both a knob-operated and double-sided key cylinder.

A distinguishing feature of this set is its inclusion of six computer-drilled symmetric keys, which enable convenient multi-door access management using a single key profile. This reduces key burden for users and simplifies facility access control, making it a practical choice for bulk procurement in residential apartment complexes, office suites, and property management projects where unified keying greatly streamlines operations.
