B-Harko DR STRONG Cylinder Set Black 45/55+45G/55 Keyed Alike EN 1303 6-Keys

Product Overview

The B-Harko DR STRONG cylinder set (45/55 + 45G/55, black) is designed for access control in residential and commercial buildings, allowing two doors or two lock points to be serviced by a single key. It complies with PN-EN 1303:2015-07 standard, assuring buyers of minimum 100,000 operating cycles, high resistance to corrosion, and security classification. The set is suitable for aluminium, PVC, or wooden doors, functioning reliably between -20°C and +80°C.

This set differentiates itself by including two types of cylinders ? one with an ergonomic thumbturn for easy manual operation and one double-sided ? with all cylinders keyed alike and supplied with six computer-milled keys. The one-key system significantly reduces management complexity for facility operators, property managers, and procurement teams outfitting multiple access points. It is particularly suited for bulk installation in new build residential blocks, multi-tenant offices, and for projects requiring unified keying across several doors.
