Product Overview

The DORMA PURE 8100/3020/6501 6612PZ fixed knob handle with round escutcheon is manufactured from stainless steel and designed for installation on left-handed wooden or profiled doors with a thickness of 38?60 mm. It fulfills PN-EN 1906 standards, including category 3 usage (high-frequency commercial environments), durability class 7 (200,000 test cycles), fire resistance class B (suitable for fire and smoke doors), and corrosion resistance class 4 (very high). The mounting screw spacing is 38 mm with an 8 mm spindle for compatibility with standard European lock configurations.

The integrated spring return mechanism distinguishes this model, ensuring the handle consistently returns to its neutral position after operation?an important feature that prevents drooping and maintains long-term functionality in high-use locations. This makes it particularly suitable for public buildings and high-traffic commercial facilities seeking certified hardware for frequent-use doors, especially where fire and corrosion resistance are project requirements.
