B-Harko DR STRONG Cylinder Set 35/30 + 35G/30 Black Keyed-Alike PN-EN 1303 Brass

Product Overview

B-Harko DR STRONG 35/30 + 35G/30 cylinder set is designed for access control in commercial and residential door installations, featuring black matte finish and computer-milled keys. Certified to PN-EN 1303:2015-07, this cylinder set includes one thumb-turn (gałka) cylinder and one double cylinder, both made entirely from brass and engineered for a minimum durability of 100,000 operating cycles. It is suitable for environments requiring robust security and frequent use, with tested performance from -20°C to +80°C.

What distinguishes this set is the keyed-alike system: six precision-milled keys operate both cylinders, streamlining facility management and reducing the number of keys in circulation. This feature minimizes risk of lost keys and simplifies access logistics, which is especially valuable for small business premises, offices, multi-unit dwellings, or facility managers overseeing several doors. Recommended for bulk procurement where shared access and efficient key management are priorities.
