Łucznik E8 30/50 Cylinder Lock Insert Class C 6.D Certified Anti-Snap Satin Nickel

Product Overview

The Łucznik E8 30/50 cylinder lock insert is a certified high-security component designed for internal and external door installations in commercial and residential buildings. Rated class C for burglary resistance and awarded certification 6.D from the Institute of Precision Mechanics, it is also approved for use in fire doors. The insert is manufactured from brass, compatible with master key and keyed-alike systems, and delivers durability exceeding 100,000 operating cycles.

A standout feature of this particular model is its active anti-snap and anti-bumping protection mechanism, which uses an automatic blocking element to prevent forced manipulation and block entry attempts when tampering is detected. This eliminates procurement risk in high-security projects where advanced protection requirements must be documented and reduces liability for facility managers. It is specifically recommended for bulk contracts in office complexes, multi-unit residential developments, and institutional facilities requiring standardised access control.
