Łucznik E8 35/40 Profile D Cylinder Lock 6.D Certified Nickel Master Key Compatible

Product Overview

Łucznik E8 35/40 is a profile D type cylinder lock insert designed for use in fire-rated, internal, and external doors within both commercial and residential properties. It holds a 6.D certificate for burglary resistance (class C, attack resistance level D) as granted by the Institute of Precision Mechanics, confirming its compliance with rigorous Polish security standards. Enhanced with anti-bumping and anti-snap defences, it provides reliable protection for high-security environments where durability and resistance to forced entry are critical.

The standout feature of this model is its compatibility with Master Key and Keyed Alike systems, allowing facility managers or large building operators to efficiently centralize key management across numerous access points. This significantly reduces the complexity and cost of maintaining individual keys in hotels, office towers, and large multi-tenanted properties. Such integration capability makes the Łucznik E8 particularly suited for bulk procurement in projects demanding centralized security infrastructure.
