Product Overview

The Łucznik E8 30/45 cylinder lock insert is a high-security profile cylinder used in both residential and commercial doors, including fire-rated, internal, and external doors. Certified to resistance class C and grade D against burglary (atest 6.D), and approved by the Instytut Mechaniki Precyzyjnej, it complies with current Polish security standards for demanding environments.

A distinguishing feature of this model is the anti-bumping and anti-snap protection with an automatic self-locking mechanism that activates when the insert is tampered with. This function reduces the risk of unauthorized entry and system failures during installation or over its operational lifespan. Building managers and facility operators benefit from reliable access control, especially when implementing Master Key or One Key systems for larger properties. The product is recommended for high-security commercial installations, property complexes, or fire-protection applications.
