NEMEF 1769/46 Panic Lock D-Type Split Spindle Stainless Steel for Doors 200kg+ Left

Product Overview

The NEMEF 1769/46 panic lock is a stainless steel mortise lock designed for high-traffic public buildings, especially where fire-rated or smoke-control door assemblies are required, subject to positive assessment. Built for robustness and frequent use, it successfully completed 200,000 test cycles under a latch load of 25N and functions reliably with doors weighing over 200 kg and closing forces up to 50N.

What sets this SKU apart is its D-type anti-panic function, allowing for instant egress from the inside via lever or handle regardless of locking status, with flexible access logic for the outside. This feature addresses safety compliance and eliminates regulatory risk for projects in facilities such as hospitals, schools, and transport hubs. Particularly suited for bulk specification in public sector and commercial installations requiring high security and panic escape functionality.
