ABUS X12 Cylinder Lock 50/55 mm SKG DIN 18252 EN 1303 Emergency Function Nickel

Product Overview

The ABUS X12 50/55 anti-burglary cylinder lock, certified to SKG, DIN 18252, DIN EN 1303, and ITB class 6.D, is intended for professional security installations in commercial, OEM, and public sector projects requiring high protection against unauthorized access. Its nickel finish and dual-length sizing (50/55 mm) allow for compatibility with doors equipped with reinforced escutcheons and fire-rated requirements. Each cylinder features patent protection until 2030, with a system of paracentric, drilled keys increasing operational comfort and minimizing wear.

What sets the ABUS X12 apart is its emergency function (secure clutch), enabling exterior access even if a key remains inserted inside, a critical requirement for multi-residential and institutional buildings where emergency personnel or maintenance must retain entry access. This particular feature eliminates lockout risk and meets facility management mandates for compliance in public-use and high-traffic environments. Especially suited for bulk procurement in commercial real estate, public facilities, and OEM fire-rated door assemblies.
