B-Harko H6 Cylinder Lock 35g/45 mm Brass with Knob EN 1303 Corrosion Class C

Product Overview

The B-Harko H6 Cylinder Lock 35g/45 mm with knob is a brass door insert designed for modern interiors, certified by the Building Research Institute under PN: EN 1303:2015-07. Featuring a 6.0 durability class and tested for a minimum of 100,000 cycles, it is suited for residential and commercial doors requiring high resistance to corrosion and temperature fluctuations from -20°C to +80°C. The lock provides advanced security with 6 pin tumblers and achieves key security class 6 for at least 100,000 key combinations.

Its standout feature is the corrosion resistance rating (class C), which enables secure operation in environments where humidity, temperature shifts, or chemical exposure would quickly degrade standard cylinder locks.
